Solution

Dear Student
The oxygen source i.e., water is about 800 times denser than air. It contains less O₂ as compared to air. Since the content of O₂in water is low, aquatic animals breathe faster to get as much oxygen as possible, resulting in a faster rate of breathing. Therefore, aquatic animals breathe faster than terrestrial animals and also show different adaptations for better gaseous exchange.
