What is a food chain?



  1. 0 Votes

    Food chains deal with how organisms interact with one another within a ecosystem when it comes to diet. All food chains begin with an autotroph, such as a plant, which then provides food for certain organisms, which in turn provides food for other organisms, and so on. Organisms involved in a food chain include heterotrophs such as herbivores and carnivores, as well as scavengers and decomposers.

    The food chain describes the order of species of animals that are consumers. It starts with the primary consumers of primary producers such as plants. From primary consumers, the food chain or web depicts how predation occurs between different species. For example humans are at the top of the food chain because we are able to consume almost any plant and animal. A simple example can be the following:

    Insects can eat plants or scavenge on dead animal matter, fish can eat some insects, bigger fish can eat the smaller fish, and large predatory birds eat the bigger fish.
