Question

Heya♥
Why is the rate of breathing in aquatic organism much faster than that seen in terrestial organism?...♥ ^_^​

Answer 1

Aquatic animals have gills for respiration. They breath oxygen mixed in water but the amount of oxygen in water is lesser than the air. So, terrestrial animals does not need to breath faster than aquatic animals.

Answer 2

ANSWER :

▶ The rate of breathing in aquatic organisms is much faster because they need more amount of air inside their body because the dissolved amount of oxygen in water is lower than air . In air the amount of oxygen is more and hence more number of breathes need to be taken by a normal aquatic organism than terrestrial organisms .

↪ Terrestrial organisms are organism which live in lands .

↪ The aquatic organisms live in water .

↪ In air the dissolved oxygen is fair enough .

↪ In water the dissolved oxygen is lower .

↪ Hence more faster rate of breathing is observed in aquatic organisms .
