What advantage over an aquatic organism does a terrestrial organism have with regard to obtaining oxygen for respiration?
Answers
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.
Answer:
Aquatic animals use the oxygen dissolve in water to carry out respiration.
Explanation:
Animals living in water need use the oxygen dissolve in water . However the amount of dissolve in oxygen is fairly low compare to the amount of oxygen in the air, hence the aquatic animals much faster breathing . Terrestrial organism , on the other hand, obtain oxygen from the oxygen -- rich atmosphere throw respiratory organ, so they breath at lesser rate than aquatic organisms .
