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:
    A condensation Correct Answer Incorrect Answer
    B evaporation Correct Answer Incorrect Answer
    C sublimation Correct Answer Incorrect Answer
    D diffusion Correct Answer Incorrect Answer

    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.
