Which of the following is a disadvantage of gas exchange in water, as compared to gas exchange in air?

A) Air is less dense than water.
B) Air contains a higher concentration of oxygen.
C) Less energy is needed to move air over a gas exchange surface.
D) Oxygen diffuses more slowly through water than air.
E) Air is less viscous than water.

Gas Exchange

The biological process through which organisms exchange gases (such as oxygen and carbon dioxide) with their environment, crucial for respiration.

Diffuses

The process by which molecules move from an area of higher concentration to an area of lower concentration.

Viscous

A physical property describing a fluid's resistance to flow, with higher viscosity indicating a thicker and slower-moving fluid.
