Question

what advantage over an aquatic organism does a Terrestrial organism have with regard to obtaining oxygen for respiration​

Answer 1

Answer:

The concentration of oxygen in the atmosphere is much higher than the concentration of oxygen present in water. Therefore, the rate of respiration in aquatic animals is much faster than the terrestrial animals.

Answer 2

Answer:

Terrestrial organisms breathe by using atmospheric oxygen whereas aquatic organism take oxygen dissolved in water. Oxygen level is high in atmosphere when compared to oxygen in water. Hence terrestrial organism need not breathe fast to obtain organism whereas aquatic organisms need to breathe faster to get required oxygen
