Are segmenteed worms scavengers

Diffusion is the way in which segmented worms breathe.

Specifically, the process in question draws upon the permeable skin surface of the segmented worm. A segmented worm's skin is capable of expeling carbon dioxide as waste and taking in oxygen for respiration. To do so, a segmented worm nevertheless must live in a humid, moist environment so that the skin does not dry out and become impermeable.
