Food Chains
Grade 3 · Science · Ecosystems · Alabama, USA
Lesson Summary
A food chain shows the order in which living things eat other living things to get energy.
Explanation
Energy in a food chain starts with the sun. Plants use sunlight to make food, so they are at the beginning of most food chains. An animal that eats the plant gets energy from it. Then a bigger animal might eat that animal. For example: grass is eaten by a rabbit, and the rabbit is eaten by a hawk. Each step passes energy along the chain.
