Answer:
Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals obtain oxygen from water. Air contains more O2 as compared to water. Since the content of O2 in the air is high, the terrestrial animals do not have to breathe faster to get more oxygen
Step-by-step explanation:
Aquatic animal like fishes has to talk up the dissolved oxygen that is present in the water. And the amount of oxygen that is dissolved from the atmosphere to water is less compared to the concentration of the oxygen that is present in the air. Also, the solubility of the oxygen in the water varies depending on the temperature and pressure on the water surface.
Aquatic animals, therefore, have to breath very fast in order to provide their body with thee required the amount of oxygen. Some of the fishes have even developed the alternate way of breathing by coming up to the water surface and take a large gulp of air and then dive below water.
Terrestrial animals whereas are provided with an atmosphere which is rich in oxygen and they have intake and outtake of the air just depending on the difference in the pressure inside the lungs and the outside temperature.
Therefore less of their energy is used and they can utilize their food energy compared to how aquatic animals utilize their energy.
