Question

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

Answer 1

aquatic organisms breath in water where amount of oxygen is less whereas terrestrial organisms breath through atmosphere that's why the breathing rate of aquatic animals is faster than of the terrestrial organisms
