    Are you talking about corporate distribution or what animals eat?

    Based on my understanding of the words, a food web would be a group of different stores that are within the same industry, but aren’t owned by same company. A food chain is a group of the same store.

    Good question, Cason, the answer is yes, there is a difference.  A food chain is a linear diagram that goes from the bottom up.  For example, a cricket is eating by a lizard, a lizard is eaten by a bird, and so on.  A food web, on the other hand, shows how many different plants and animals survive by consuming each other.  Here are a couple of diagrams to help visualize these ideas:

    Food chains are much less complex than food webs.  A food chain shows a very simple chain of consumption.  A food web contains more than one food chain.  They usually define entire ecosystems or environments.

    A food chain only shows one vertical line of who is eaten by whom.  Like the nut is eaten by the squirrel which is eaten by the hawk and so on.  The food chain is very basic and doesn’t show the full picture of an ecosystem.  A food web on the other hand refers to everything that goes on.  For example, a mouse is prey to multiple animals.  Some of the animals that are predators to mice are also prey to other predators of mice.  The food web shows the connection between everything.

    Think of a food chain as just one part of the food web. A good way to think about it is if you were looking at your family. An example of a chain would be your grandparents had one of your parents and then your parents had you. This chain totally excludes the cousins, aunts, uncles, and even your own siblings! A web gives the whole picture!

    There is a difference between a food web and a food chain. A food chain is a simplier diagram, showing only one way energy reached the top consumer. It usually only contains a few links, and begins at the bottom with the primary producer. From there, it shows who eats whom, until the top consumer is the last one to eat anything. A food web, on the other hand, is a combination of multiple food chains. It is more complex, but more indicitive of the real world, as chains oftentimes overlap. The energy still goes from a primary producer to the top consumer, but it shows the multiple routes it may travel to get there.

    A food chain is far more linear, showing a progression of events, whereas a food web shows the relationship between different organisms and the relationship between the food of that organism and other organisms.

    A food chain is the order that animals eat one another, and a food web is a map of which animals eat what. Hope this helps! :D

    yes , there is ,

    A food chain is a single line of organisms, where each is preceded by something that it consumes and is followed by something that consumes it. A food web branches out in all directions with arrows pointing from organisms to any number of organisms that consume it.
    hope this help’s ;)

    Food chains are singular – bugs eat leaves, birds eat bugs, snakes eat birds.  Food WEBS show the interconnectivity of the biosphere:

    • TREES produce ACORNS which act as food for many MICE and INSECTS.
    • Because there are many MICE, WEASELS and SNAKES have food.
    • The insects and the acorns also attract BIRDS, SKUNKS, and OPOSSUMS.
    • With the SKUNKS, OPPOSUMS, WEASELS and MICE around, HAWKS, FOXES, and OWLS can find food.
    • They are all connected! Like a spiders web, if one part is removed, it can affect the whole web.

    A food chain could be considered a simplified version of a food web, in that it shows the linear progression of which animals depend on others for sustenance. In a sense, a food chain portrays the hierarchy of predatory animals in an ecosystem, emphasizing the element of competition and the “survival of the fittest” perspective of natural systems.

     

    A food web, on the other hand, is a more elaborate net of the interrelatedness of animals in an ecosystem. It more clearly depicts the complexity of organisms and how they depend on each other in an ecosystem, rather than ranking animals solely by which animal is eaten first. Because of this, it comes closer to a true image of natural systems.

     

    While in the linear format of a food chain animals may appear to be “dominant” over others, in a food web they are exhibited as interdependent with the other animals, creating an image of complexity and nuance that more closely approximates the elaborateness and intricacy of nature.

    FOOD CHAINS FOLLOW A SINGLE PATH AS ANIMALS EAT EACH OTHER.
    EXAMPLE:

     

    • THE SUN provides food for GRASS
    • The GRASS is eaten by a GRASSHOPPER
    • The GRASSHOPPER is eaten by a FROG
    • The FROG is eaten by a SNAKE
    • The SNAKE is eaten by a HAWK.

    FOOD WEBS SHOW HOW PLANTS & ANIMALS ARE INTERCONNECTED BY DIFFERENT PATHS.
    EXAMPLE:

    • TREES produce ACORNS which act as food for many MICE and INSECTS.
    • Because there are many MICE, WEASELS and SNAKES have food.
    • The insects and the acorns also attract BIRDS, SKUNKS, and OPOSSUMS.
    • With the SKUNKS, OPPOSUMS, WEASELS and MICE around, HAWKS, FOXES, and OWLS can find food.
    • They are all connected! Like a spiders web, if one part is removed, it can affect the whole web. 

     

    FOOD WEBS show how plants and animals are connected in many ways to help them all survive. FOOD CHAINS follow just one path of energy as animals find food.

    As far as I know, the two are different but quite related. A food chain is more linear while a food web involves a broader group of species, including multiple food chains. As many of us may have learned at a young age, food chains literally trace down a totem pole of predators and prey in a particular ecosystem.  A general example of a food chain would be something like shark, to fish, to smaller fish, to plankton. Meanwhile a food web constitutes the interrelated lifestyles and habits–so, this would include food chains but also other information about how each creature benefits the next.'Sample Food Chains'‘Sample Food Chains’

    Yes. A food chain is a chain and therefore oneway only. However a food web is a web and shifts. For example a bird might eat worms, a raccoon eats that bird, and a worm eats the raccoon when it dies. You see, it’s a cycle.

    food webs are totally diffrent!! food webs are the entire ecosystem food webs are mostly those perticular animals.

    A food chain has been linked to animals directly eating each other. Food webs are certain types of animals going out of their food chain to eat other animals too. Some of these webs are known to link directly to many different animals. An environment can distrub the web to cause animals to find other animals to eat. Food ChainFood weba food web can link to all kinds of animals together due to their environmental factor. The factor can cause them to rely on other animals for survival. Part of an environmental factor can inlcude climate change and multiple destruction of land by human purposes. The main climate change includes the greenhouse effect Greenhouse effect

    The food chain consists of four main parts:

    • The Sun, which provides the energy for everything on the planet.
    • Producers: these include all green plants.  These are also known as autotrophs, since they make their own food.  Producers are able to harness the energy of the sun to make food.  Ultimately, every (aerobic) organism is dependent on plants for oxygen (which is the waste product from photosynthesis) and food (which is produced in the form of glucose through photosynthesis).  They make up the bulk of the food chain or web.
    • Consumers: In short, consumers are every organism that eats something else.  They include herbivores (animals that eat plants), carnivores (animals that eat other animals), parasites (animals that live off of other organisms by harming it), and scavengers (animals that eat dead animal carcasses).  Primary consumers are the herbivores, and are the second largest biomass in an ecosystem.  The animals that eat the herbivores (carnivores) make up the third largest biomass, and are also known as secondary consumers.  This continues with tertiary consumers, etc.
    • Decomposers: These are mainly bacteria and fungi that convert dead matter into gases such as carbon and nitrogen to be released back into the air, soil, or water.  Fungi, and other organisms that break down dead organic matter are known as saprophytes.  Even though most of us hate those mushrooms or molds, they actually play a very important role.  Without decomposers, the earth would be covered in trash.  Decomposers are necessary since they recycle the nutrients to be used again by producers.food web (or food cycle) depicts feeding connections (what eats what) in an ecological community. Ecologists can broadly lump all life forms into one of two categories called trophic levels: 1) the autotrophs, and 2) the heterotrophs. To maintain their bodies, grow, develop, and to reproduce, autotrophs produce organic matter from inorganic substances, including both minerals and gasessuch as carbon dioxide. These chemical reactions require energy, which mainly comes from the sun and largely by photosynthesis, although a very small amount comes from hydrothermal vents and hot springs. A gradient exists between trophic levels running from complete autotrophs that obtain their sole source of carbon from the atmosphere, to mixotrophs (such as carnivorous plants) that are autotrophic organisms that partially obtain organic matter from sources other than the atmosphere, and complete heterotrophs that must feed to obtain organic matter. The linkages in a food web illustrate the feeding pathways, such as where heterotrophs obtain organic matter by feeding on autotrophs and other heterotrophs. The food web is a simplified illustration of the various methods of feeding that links an ecosystem into a unified system of exchange. There are different kinds of feeding relations that can be roughly divided into herbivorycarnivoryscavenging and parasitism. Some of the organic matter eaten by heterotrophs, such as sugars, provides energy. Autotrophs and heterotrophs come in all sizes, from microscopic to many tonnes – from cyanobacteria to giant redwoods, and from viruses and bdellovibrio to blue whales.

    A food chain is the sequence of who eats whom in a biological community (an ecosystem) to obtain nutrition. A food chain starts with the primary energy source, usually the sun or boiling-hot deep sea vents. The next link in the chain is an organism that make its own food from the primary energy source — an example is photosynthetic plants that make their own food from sunlight (using a process called photosynthesis) and chemosynthetic bacteria that make their food energy from chemicals in hydrothermal vents. These are called autotrophs or primary producers.

    Next come organisms that eat the autotrophs; these organisms are called herbivores or primary consumers — an example is a rabbit that eats grass.

    The next link in the chain is animals that eat herbivores – these are called secondary consumers — an example is a snake that eat rabbits.

    In turn, these animals are eaten by larger predators — an example is an owl that eats snakes.

    The tertiary consumers are are eaten by quaternary consumers — an example is a hawk that eats owls. Each food chain end with a top predator, and animal with no natural enemies (like an alligator, hawk, or polar bear).

    The arrows in a food chain show the flow of energy, from the sun or hydrothermal vent to a top predator. As the energy flows from organism to organism, energy is lost at each step. A network of many food chains is called a food web.

    Trophic Levels:
    The trophic level of an organism is the position it holds in a food chain.

    1. Primary producers (organisms that make their own food from sunlight and/or chemical energy from deep sea vents) are the base of every food chain – these organisms are calledautotrophs.
    2. Primary consumers are animals that eat primary producers; they are also called herbivores (plant-eaters).
    3. Secondary consumers eat primary consumers. They are carnivores (meat-eaters) and omnivores (animals that eat both animals and plants).
    4. Tertiary consumers eat secondary consumers.
    5. Quaternary consumers eat tertiary consumers.
    6. Food chains “end” with top predators, animals that have little or no natural enemies.

    When any organism dies, it is eventually eaten by detrivores (like vultures, worms and crabs) and broken down by decomposers (mostly bacteria and fungi), and the exchange of energy continues.

    Some organisms’ position in the food chain can vary as their diet differs. For example, when a bear eats berries, the bear is functioning as a primary consumer. When a bear eats a plant-eating rodent, the bear is functioning as a secondary consumer. When the bear eats salmon, the bear is functioning as a tertiary consumer (this is because salmon is a secondary consumer, since salmon eat herring that eat zooplankton that eat phytoplankton, that make their own energy from sunlight). Think about how people’s place in the food chain varies – often within a single meal.

    Numbers of Organisms:
    In any food web, energy is lost each time one organism eats another. Because of this, there have to be many more plants than there are plant-eaters. There are more autotrophs than heterotrophs, and more plant-eaters than meat-eaters. Although there is intense competition between animals, there is also an interdependence. When one species goes extinct, it can affect an entire chain of other species and have unpredictable consequences.

    Equilibrium
    As the number of carnivores in a community increases, they eat more and more of the herbivores, decreasing the herbivore population. It then becomes harder and harder for the carnivores to find herbivores to eat, and the population of carnivores decreases. In this way, the carnivores and herbivores stay in a relatively stable equilibrium, each limiting the other’s population. A similar equilibrium exists between plants and plant-eaters.

    Therefore the above were the couple of excellent sources of Vitamin B12 . We’d like to explain to you regarding several foods loaded with iron, too. The reason? Hardly any individuals understand the idea that if somebody endures Vitamin B12 deficit, he or she grows more at risk of poor in iron. Once more why? These vitamins work together inside their tasks in the system. Thus, enjoying a diet plan containing more vitamin B12 foods is just not good enough. You need to pay equivalent attention to the necessity of iron.

    If you’re unaware, deficiency of Vitamin B12 can result in the growth of illnesses just like anemia along with neurological injury, and also signs or symptoms for instance despression symptoms, low energy, mind problems, a pounding heart, some weakness, and many others. Thus, continue the ranges of this sort of vitamin, actually most vitamins as well as mineral deposits, and be healthy!

    Good question, the answer is yes.  A food chain is a linear diagram that starts from the bottom up. As example, a lady bug is eaten by a lizard, a lizard is eaten by a bird, and so it gose on untill it will eventally stop. A food web, on the other hand, shows how many different plants and animals survive by eating others. Here see mine, we had to do these in class and mine were some of the best.

    yes there is a difference between afoood chain and a food web.A food chain is a linear sequence of links in a food web starting from trophic species that eats no other species in the web and ends at a trophic species that is eaten by no other species in the web.While a food web depicts feeding connections(what eats what)in an ecological communityand hence is also referred to as a consumer-resource system.
