Question

why do aquatic animals have a faster rate of breathing compared to Terrestrial animals

Answer 1

The breathing rate of aquatic animals is faster than that of terrestrial animals because the amount of dissolved oxygen in the water in much less than the amount outside, so they have to breathe more in order to get more oxygen. 

Hope it helps :)

Answer 2

Hey dear ,

Aquatic animals have a faster rate of breathing as compared to terrestrial animals because ,

The amount of oxygen dissolved in a the water is low and hence it takes lot of energy and time to breath, and the rate of breathing is faster .

For terrestrial animals , we know that in atmosphere there is good amount or rate of oxygen is present this helps to take oxygen in systematic manners and with comfort so the rate of breathing is slow.
