Question

Match the organisms with the correct organs of respiration.

• A. skin
• B. lungs
• C. gills
• D. spiracles

Answer 1

Earthworms use their skin to absorb oxygen from air and remove carbon dioxide. So, the respiratory organ in the earthworm is the skin. In the insects like grasshopper, cockroach, housefly and mosquito, tiny holes called spiracles on the sides of their body are the respiratory organs. Fish have gills as the respiratory organs. Humans have lungs.
