Why is diffusion important in aquatic life?

Diffusion is crucial for aquatic life as it facilitates the movement of essential substances, such as oxygen and nutrients, from areas of higher concentration to lower concentration within the water. This process enables aquatic organisms, particularly those with limited mobility, to absorb the oxygen they need for respiration and other vital functions. Additionally, diffusion aids in the removal of waste products, helping to maintain a balanced and healthy environment for marine ecosystems. Overall, diffusion supports the survival and growth of various aquatic species.
