Question

i need the answer by the end of the week

Answer 1

They feed on dirt and the mineral salts and water in the earth provides them with nourishment. They also respire through their skin.

Answer 2

1. They have a closed circulatory system that distributes nutrients throughout the body.
2. They eat undecayed plant matter and convert it to humus (they act as decomposers).
3. The mouth connects directly to the digestive tract (unlike humans with the esophagus).
4. Worms shred their food before eating it; the crop grinds it into a fine paste with the help of particles of grit; food is saturated with intestinal secretions; then it's digested in the stomach.
