Why is there a difference in the rate of breathing between aquatic organisms and terrestrial organisms? Explain.

Explanation

There is a difference between the rate of breathing between aquatic organisms and terrestrial organisms because animals living in water need to use the oxygen dissolved in water whereas terrestrial animals can breathe the oxygen in the atmosphere. Therefore, the amount of dissolved oxygen in water is much less to the amount of oxygen in the air or in the land, so they have to breathe more inorder to get more oxygen.
