What advantage over an aquatic organism does a terrestrial organism have with regards to obtaining oxygen for respiration?

Question

Answer

Aquatic organism take up oxygen which is dissolved in water as the amount of oxygen is limited in water aquatic organisms has to adopt gaseous exchange method to get more oxygen , where as terrestrial organism take up oxygen from the atmosphere as the amount of oxygen is more in air as compared  to water terrestrial organisms does not need to adapt gaseous exchange.

Answer

Actually the solubility of oxygen in water is less, there is not much oxygen available for aquatic organisms and so, they have to breathe at a faster rate.And this may work as advantage for them.

Answer

Advantages of Terrestrial Organisms in Obtaining Oxygen for Respiration

Terrestrial organisms are those that live on land as opposed to aquatic organisms that live in water. The ability to obtain oxygen for respiration is an essential factor that determines the survival and growth of an organism. Terrestrial organisms have several advantages over aquatic organisms when it comes to obtaining oxygen for respiration. These advantages are discussed below.

Protected Air Supply
One of the advantages of terrestrial organisms is that they have a protected air supply. Unlike aquatic organisms that rely on the dissolved oxygen in water, terrestrial organisms breathe air directly from the atmosphere. The air supply is not only abundant but also protected from changes in temperature, pressure, and oxygen concentration. This ensures that the oxygen supply is constant, which is essential for the proper functioning of the respiratory system.

Efficient Oxygen Extraction
Terrestrial organisms have evolved efficient mechanisms for extracting oxygen from the air. They have specialized respiratory organs such as lungs and tracheae that allow for the efficient exchange of gases between the organism and the environment. The respiratory organs are also protected from waterlogging, which can interfere with gas exchange.

Reduced Competition
Terrestrial organisms have reduced competition for oxygen compared to aquatic organisms. In water, oxygen is dissolved and shared among all living organisms in the ecosystem. This can lead to competition for oxygen, especially in areas where the water is stagnant or polluted. Terrestrial organisms, on the other hand, have access to unlimited air supply, which reduces competition for oxygen.

Increased Mobility
Terrestrial organisms have increased mobility compared to aquatic organisms. This allows them to move to areas with high oxygen concentration, which is essential for survival. Terrestrial organisms can also move away from areas with low oxygen concentration or areas that are polluted, which is not possible for aquatic organisms.

Conclusion
In conclusion, terrestrial organisms have several advantages over aquatic organisms when it comes to obtaining oxygen for respiration. These advantages include a protected air supply, efficient oxygen extraction, reduced competition, and increased mobility. These adaptations have allowed terrestrial organisms to thrive in diverse habitats and environments.
