3 What is food chain? A food chain shows how each living thing gets its food. Some animals eat plants and some animals eat other animals.

A food chain always starts with plant life and ends with an animal. Wong, A. (n.d.). Food chains and webs. Retrieved July 4, 2006, from http://www.vtaide.com/png/foodchains.htm
