Advantage of Terrestrial Animals over Aquatic Animals in Obtaining Oxygen for Respiration Terrestrial animals are those that live on land, while aquatic animals are those that live in water. Both types of animals need oxygen for respiration, but terrestrial animals have an advantage over aquatic animals in obtaining oxygen. Greater availability of oxygen in air One of the main advantages of terrestrial animals is that they have greater access to oxygen in the air. The concentration of oxygen in air is about 21%, while the concentration of dissolved oxygen in water is much lower, usually ranging from 1 to 10 mg/L. This means that air-breathing animals can take in more oxygen per breath than aquatic animals, which have to extract oxygen from the water. Efficient respiratory system Terrestrial animals have evolved efficient respiratory systems to take in oxygen from the air. For example, birds have lungs that are much more efficient than those of mammals, allowing them to extract more oxygen from each breath. In addition, many terrestrial animals have developed specialized organs such as gills, which increase the surface area available for oxygen exchange. Less competition for oxygen Another advantage of terrestrial animals is that they face less competition for oxygen than aquatic animals. In water, many organisms are competing for the same pool of oxygen, which can limit the amount of oxygen available to each organism. Terrestrial animals, on the other hand, have access to ...

• Air contains about 21% oxygen while water has 1% oxygen in dissolved state. • A terrestrial organism is able to get several more times oxygen than an aquatic animal and have an advantage over them. • 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.

The difference between aquatic and terrestrial respiration is as follows: Aquatic respiration Terrestrial respiration Occurs in organisms living in water Occurs in land organisms Involve oxygen which is dissolved in water Does not involved dissolved oxygen Main respiratory organ is gills Main respiratory organ is generally lungs Gills are tough and spiny Lungs are moist, slippery and soft. Breathing rate is comparatively higher Breathing rate is comparatively lower

Terrestrial organisms take up oxygen from the atmosphere whereas aquatic animals obtain oxygen from water. Air contains more O 2as compared to water. Since the content of O 2in air is high, the terrestrial animals do not have to breathe faster to get more oxygen. Therefore, unlike aquatic animals, terrestrial animals do not need adaptations for gaseous exchange.

For this reason, aquatic animals breathe faster to obtain as much oxygen as possible, on the other hand, terrestrial animal does not have to breathe faster and thus spends less energy than aquatic organism.
