Question

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

Answer 1

Terrestrial organisms:

1. Terrestrial creatures are organisms that reside on the land.
2. In terms of acquiring oxygen for breathing, terrestrial species breathe through atmospheric oxygen.

Advantages for terrestrial animals over aquatic animals:

1. When compared to oxygen in water, air comprises 21% of oxygen.
2. While water contains less than or equal to 1% of oxygen, which makes them less available for oxygen.
3. This lesser oxygen concentration also affects creatures' breathing rate.
4. Aquatic animals breathe at a faster rate than compared to terrestrial ones.
5. This is because a larger concentration of oxygen is available for land animals than for aquatic ones.
6. As a result, a terrestrial species has an advantage over an aquatic animal in terms of breathing oxygen.
