Question

What are advantages of terrestrial organisms over aquatic organisms with regard to oxygen for respiration?​

Answer 1

Answer:

Terrestrial organisms breathe by using atmospheric oxygen whereas aquatic organism take oxygen dissolved in water. 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.

Answer 2

Answer:

Respiration for terrestrial organisms is easier.

Explanation:

Aquatic animals use oxygen dissolved in the water. As the temperature of water increases, the solubility of oxygen decreases. This results in difficulty in respiration. On the other hand, the respiration on land doesn't depend on the temperature on land as the oxygen's solubility in air isn't affected by the temperature or any other external factors.

Hope this answer helps you.
