Question

The two organisms which breath only through their moist skin are ______.

पर्याय

• fish and frog

• frog and earthworm

• leech and earthworm

• fish and earthworm

Answer 1

Leech and Earthworm

Explanation:

Both leeches and earthworms lack specialized respiratory organs like lungs or gills. Instead, they perform gaseous exchange entirely through their thin, moist, and highly vascularized skin (a process called cutaneous respiration). Oxygen from the air or water dissolves in the moisture on their skin and diffuses directly into their bloodstream.
