Question

through which does fish respire?​

Answer 1

Answer:

Through gills fish respire

Answer 2

Answer:

gills

Oxygen and carbon dioxide dissolve in water, and most fishes exchange dissolved oxygen and carbon dioxide in water by means of the gills.

Explanation:

Instead of breathing air, fish must get their oxygen from the water. This process requires large volumes of water to pass through absorption surfaces to get enough oxygen into their bodies using their mouths and gills. These body parts work like a pump to keep water moving over the gas absorption surfaces of the gills.
