However, some researchers describe them as detrivores, meaning that they eat decaying plants and animals. Earthworms eat small micro-organisms and organic matter and will feed on dead leaves and grass while on the surface of the ground. Worm casts contain partially digested nutrients, which allows plants to use those nutrients more readily.
