When you need energy in the morning before you come to school what do you do? Eat breakfast. Review that living things need food to give them energy. Plants get energy from sunlight. Grasshoppers get their energy from plants. Birds get their energy from grasshoppers. Draw the food chain on the board as you go along. Explain that this is a food chain. The plants and animals in a food chain depend on each other to live. What would happen if all the plants died? (Erase plants from board) Can grasshoppers get their food or energy from the sun? No. The grasshoppers would die. (Erase the grasshoppers) All the animals that eat/ depend on the grasshoppers would die too. So every part of the chain is important.
