Question

why is the rate of breathing much faster in aquatic and organisms than those of Terrestrial organisms

Answer 1

Because the dissolved oxygen in water is not sufficient for aquatic animals at once so they have to breath faster so that they can get sufficient supply of oxygen. Hence, the rate of breathing is faster in aqautic animals is faster than that of terrestrial animals

Answer 2

$<b>The amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air. So the rate of breathing in aquatic organisms is much than faster than Terristrial animals.$
