Question

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

Answer 1

Answer:

• Aquatic organisms like fishes obtain oxygen from water present in dissolved state through their respiratory organ gills.
• Since the amount of dissolved oxygen in water is low compared to the amount of oxygen in the air, the rate of breathing in aquatic organisms is much faster because of the low concentration of oxygen in the aquatic environment than that seen in terrestrial organisms.
