Answers
Answer:

Answer:
In earthworm and leeches respiration takes place through their moist, thin and vascular skin.
Explanation:
The oxygen gas absorbed by the skin does not go directly pass through the thin outer skin. This oxygen first mix with the the moist slime on the skin and then transported to all the cells of the body.
The cells, use this oxygen for oxidation of food.
During oxidation carbon dioxide is produced. This carbon dioxide mixes in blood and diffused out of the body through the skin.
