definition: An earthworm is a long worm that loosens the soil by making tunnels.
Earthworms are helpful to plants because they break down things like dead leaves and change them into nutrients for the soil. The nutrients in the soil help the plants grow. They are like food for them. Earthworms also make little paths for water and air to go through the soil. This is also good for the plants.
