Question

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

Answer 1

The following are the advantages that a terrestrial organism will have:

Explanation:

• There is more quantity of oxygen in the air as compared to the quantity of oxygen in the water. Hence, the terrestrial organisms will have more access to oxygen as compered to the aquatic organisms.

• The oxygen in the air is in free state whereas the oxygen in the water is dissolved in water. It is more easy for a terrestrial organism to inhale fresh air than for an aquatic organism to take in oxygen in a soluble format.

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 .
