Question
Gases, especially oxygen and carbon dioxide, are
essential for the survival of aquatic animals and plants. The gases from the atmosphere reach the aquatic animals and plants through:Solution
Gases such as oxygen and carbon dioxide reach aquatic animals and plants primarily through the process of diffusion from the atmosphere into the water. This process allows these gases to dissolve into the water, where they become available for use by aquatic organisms. Oxygen is crucial for respiration in aquatic animals, while carbon dioxide is used by aquatic plants for photosynthesis. Â
