Question

the dissolved oxygen in water is fairly low as compared to the amount of oxygen in the air so why do we say that the breathing rate in aquatic animals is much faster than that of terrestrial organisms it should know it should be its opposite​

Answer 1

Answer:

Since the quantity of dissolved oxygen in water is very much less as compared to the quantity of oxygen present in the air aquatic animals can breathe only dissolved oxygen, so to fulfill the need of required amounts of oxygen to the body cells for proper functioning the aquatic animals have to breathe faster as ..

Answer 2

Explanation:

The rate of breathing in aquatic organisms is much faster than in terrestrial organisms because the amount of dissolved oxygen is fairly lower in water than air and also that aquatic organisms like the fishes obtain oxygen from water present in the dissolved state.

Since the quantity of dissolved oxygen in water is very much less as compared to the quantity of oxygen present in the air aquatic animals can breathe only dissolved oxygen, so to fulfill the need of required amounts of oxygen to the body cells for proper functioning the aquatic animals have to breathe faster as compared to terrestrial animals.
