What Is a Food Chain?
Everything that is alive needs food. You eat to stay alive. You need food so you can grow. Your body changes food into energy. You use energy when your heart beats. You use energy when your lungs take in air. You need energy to walk and talk. You need energy to do everything!
All living things need food, too. Food and its energy move from one living thing to the next. Big fish eat little fish. Little fish eat smaller fish or plants. Food and energy move in a path we call the food chain.
