Whatadvantage over an aquatic organism does a terrestrial organism havewith regard to obtaining oxygen for respiration?

Open in App

Solution

Terrestrialorganisms take up oxygen from the atmosphere whereas aquatic animalsneed to utilize oxygen present in the water. Air contains more O₂as compared to water. Since the content of O₂in air is high, the terrestrial animals do not have to breathe fasterto get more oxygen. Therefore, unlike aquatic animals, terrestrialanimals do not have to show various adaptations for better gaseousexchange.
