A food chain shows how each living thing gets its food .Some animals eat plants and some animals eat other animals. For example, a simple food chain links the trees & shrubs) and the lions (that eat the giraffes). Each link in this chain is food for the next link. A food chain always starts with plant life and ends with an animal.
Example: Corn > a chicken > man.
Algae > a minnow> a bass >Man
