Question

1.Why a fish cannot live outside the water.answer in detail.​

Answer 1

Answer:

Though some fish can breathe on land taking oxygen from air, most of the fish, when taken out of water, suffocate and die. This is because gill arches of fish collapse, when taken out of water, leaving the blood vessels no longer exposed to oxygen in air.

Answer 2

Answer:

They have gills, which they use to filter oxygen from the water. They can't get enough oxygen on land, causing them to suffocate. Their bodies are also coated in a slime, which protects them. Out of water, this slime will dry out and cause them to die.
