Earthworms, amoebas, mites, and moles also live in the soil. As they search for food, earthworms slither through the dirt, eating debris and discharging it as a rich natural fertilizer called castings. They leave behind an underground network of tunnels that allows air and water to filter in. The air and water help the plant roots breathe and grow.

The soil provides a home for the seed, but the seed only has enough energy inside it to push the new seedling out of the soil. Then the sun takes over. Sunlight is a key ingredient in Earth’s food recipe. Plants are the only living things that can use the sun’s energy to grow.
