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

Expert Answer
Animals living in water need use the oxygen dissolved in water. However the amount of dissolved oxygen is fairly low compared to the amount of oxygen in the air. Hence, the aquatic organisms has much faster rate of breathing. Terrestrial organisms, on the other hand, obtain oxygen from the oxygen - rich atmosphere through respiratory organs. So, they breathe at a lesser rate than aquatic organisms. Thus terrestrial organisms can facilitate better utilization of food by way of respiration.
