Most flatworms take in food via their mouth, then move it into a digestive gut that attaches to the digestive structures. The food then breaks down and is absorbed out into the rest of the organism. Some have an anus to remove wastes, but most don't and will simply excrete unused food through the mouth..
Keeping this in consideration, how do free living flatworms eat?
In symbiotrophic flatworms, gases and nutrients diffuse into tissues of the flatworm from the host digestive system or from water. Free-living flatworms ingest food. Platyhelminth worms that have a gut discharge solid waste through their mouths because they lack an anus.
