Vedclass · Answer

(B) Aquatic organisms,such as fishes,obtain oxygen from water in a dissolved state through their gills.Since the concentration of dissolved oxygen in water is significantly lower compared to the concentration of oxygen in the atmosphere,aquatic organisms must breathe much faster to extract sufficient oxygen for their metabolic needs.In contrast,terrestrial organisms have easy access to the high concentration of oxygen present in the air,allowing for a slower rate of breathing.

Why is the rate of breathing in aquatic organisms much faster than in terrestrial organisms?
