Diffusion of gases in water is essential:
i. The gases from the atmosphere diffuse and dissolve in water.
ii. The gases especially oxygen and carbon dioxide are essential for the survival of aquatic animals and plants.
iii. The aquatic animals can breathe under water due to the presence of dissolved oxygen in water (diffusion of gases of atmosphere and water)
iv. Thus, we may conclude that diffusion of gases in water is essential for the survival of aquatic animals and plants.
