SkinAnswer & Solution
Answer:
Skin
Solution:
Earthworm breathes through their skin. Air dissolves on the mucus of their skin, so they must be moist in order to breathe. Again, after heavy rains earthworms surface as excess water inhibits from breathing oxygen. If they dry out and don’t surface, they suffocate and die. As fresh air is absorbed through the skin, oxygen is drawn into the worm's circulatory system, and the worm's hearts pump the oxygenated blood to the head.
