Question

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



​

Answer 1

Explanation:

A terrestrial animal has over an aquatic animal with regard to obtaining oxygen for respiration. It's because the air in the atmosphere contains the maximum amount of oxygen. Oxygen level is high in the atmosphere when compared to oxygen in water.

Answer 2

Aquatic organisms use oxygen dissolved in surrounding water . Since air dissolved in water has fairly low concentration of oxygen , the aquatic organisms have much faster rate of breathing .

Terrestrial organisms take oxygen from

the oxygen-rich atmosphere through

respiratory organs . Hence , they have

much less breathing rate than aquatic

organisms .
