Question

Why is breathing rate in aquatic organism much faster than in terrestrial organism

Answer 1

Answer:

aquatic organisms have to breath more air, as compared to terrestrial organisms.

Explanation: reason 1} on land, the concentration of oxygen in the atmosphere is 21 per cent, whereas, in water the concentration of dissolved oxygen is much lesser due to which the organisms, have to breath harder and faster to inhale adequate oxygen.

reason 2} water is heavier than air and therefore, it is harder for oxygen to easily move around. due to this, the organisms have to inhale oxygen with a faster pace and greater energy.

hope this helped......

Answer 2

Since the amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air, the rate of breathing in aquatic organisms is much faster due to the low concentration of oxygen in the environment than that seen in terrestrial organisms.
