Question

The exchange of gases with the surrounding atmosphere for respiration takes place through the skin in which of the following organisms?

Answer 1

Answer:

Tapeworm

Earthworm

Leech

Frog

Explanation:

Tapeworms, earthworms, and leeches use their skin for the exchange of gases. The skin of Earthworms is very thin and moistened. Many blood cells are spread on this skin. These blood cells are known as capillaries. The exchange of gases occurs at capillaries. They die of suffocation if their skin is dried up .

Amphibians such as frogs use more than one organ of respiration during their life. They breathe through gills while they are tadpoles. Mature frogs breathe mainly with lungs and also exchange gas with the environment through skin.
