Question

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

Answer 1

Answer:

due to less amount of o2 present in dissolved form aquatic animals have to breathe faster than terrestrial organisms

Answer 2

Explanation:

Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals obtain oxygen from water. Air contains more O2 as compared to water. Since the content of O2 in air is high, the terrestrial animals do not have to breathe faster to get more oxygen. Therefore, unlike aquatic animals, terrestrial animals do not need adaptations for gaseous exchange.
