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

Text Solution

Verified by Experts

Terrestrial organisms take up oxygen from the atomosphare whereas aquatic animals obtain oxygen from water. Air contains more `O_(2)` as compared to water. Since the conternt of `O_(2)` in air is high, the terrestrial animals do not have to breathe faster to get more oxygen. Therefore, unlike aquatic animals, thrrestrial animals do not need adptations for gaseous exchange.
