Question

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

Answer 1

Answer:

1. there is very little amount of dissolved oxygen in water while there is plenty of oxygen in air.

2. therefore Terrestrial organisms can breath easily while aquatic organism need a special mechanism for breathing

3. also their rates of breathing is greater than Terrestrial organisms due to low supply of oxygen in water.

that is the advantage over an aquatic organism exhibited by Terrestrial organisms

Answer 2

Explanation:

Adaptation of terrestrial organism over aquatic organism for efficient uptake of oxygen from air –

(i) Increased respiratory surface area.

(ii) Very fine and delicate surface for easy exchange of oxygen and carbon – dioxide.

(iii) Placement of respiratory surface within the body for protection

(iv) Mechanism for moving the air in and out of respiratory surface where the oxygen is absorbed
