What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration?

Answer»

The organism that lives in water such as a fish obtains oxygen for respiration which is dissolved in water. Whereas the terrestrial organisms take in oxygen directly from the air. Since the amount of oxygen dissolved in water is fairly low as compared to the amount of oxygen in the air, breathing rate in aquatic organisms is much faster than terrestrial organisms.
