Earthworms eat dead plants and animals. When they eat, they also take in soil and tiny pebbles. Earthworms take in nutrients from microorganisms in the material they ingest. They then excrete wastes in the form of casts.

Do annelids have a mouth?

The internal organs of annelids are well developed. They include a closed, segmentally-arranged circulatory system. The digestive system is a complete tube with mouth and anus. Gases are exchanged through the skin, or sometimes through specialized gills or modified parapodia.

How do annelids obtain and digest food?

Not only can worms continually digest their food, but they also can squirm, crawl and slither as they digest. Annelids creep along or burrow by coordinating two sets of muscles. One set allows them to expand and anchor one segment of their body.
