WHY DO AQUATIC ANIMALS BREATHE FASTER THAN TERRESTRIAL ANIMALS ?
Dear student
Aquatic animals breathe at a faster rate than the terrestrial animals because the amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air. To meet the oxygen need aquatic animals breathe faster to intake more oxygen.
The oxygen concentration in water is 21% less than the concentration of oxygen in the air.
Most fishes and amphibian species breathe through gills. Due to the lower percentage of oxygen in water, so these animals need to have more water inside their gills to extract enough oxygen, hence they breathe faster.
