A roundworm eats food that enters its mouth. The mouth signals the starting point of the digestive system. The food itself is consumed when the surrounding muscles (called pharyngeal muscles) contract, creating a vacuum-like suction.
Do roundworms absorb nutrients?

Do roundworms eat your food?
The Food Chain They are eaten but not digested, or not consumed at all.
How are nutrients transported in roundworms?
The gizzard uses stones that the earthworm eats to grind the food completely. The food moves into the intestines as gland cells in the intestine release fluids to aid in the digestive process. The intestinal wall contains blood vessels where the digested food is absorbed and transported to the rest of the body.
