Question

Why are the terestrial organisms betterly respire than aquatic?

Answer 1

terrestrial organisms respire better than aquatic organisms because the amount of oxygen(dissolved oxygen) in water is very less than in land. so

Answer 2

Aquatic animals take in the oxygen dissolved in water. The amount of dissolved oxygen in water is fairly low compared to the amount of oxygen in the air. Therefore, rate of breathing in aquatic organisms is much faster than in terrestrial organisms.
