The basic body plan of an earthworm is a tube, the digestive system, within a tube, the muscular slimy, moist outer body. Earthworms are hermaphrodites. Young are hatched from cocoons. Earthworms eat dead and decomposing leaves, decaying roots, and other bits of plant material, or detritus (dih-TRY-tuhs), in the soil.
