Deep underground and on the surface, worms are hard at work! Worms work like little plows, burrowing through soil by swallowing it. As they make their way through the dirt, worms loosen the soil so roots can spread and grow. Worms eat the bits of leaves and plants mixed with the dirt and leave behind castings that feed the plants. Find out how worms help us as they wiggle their way underground.
