explain one way in which acid rain is harmful to aquatic organisms.

Explanation:

Acid rain lowers the pH of water bodies. Aquatic organisms have specific pH ranges for survival. A lower pH (more acidic water) can disrupt their physiological processes. For example, it can affect the ability of fish to take in oxygen through their gills and can also harm the eggs and larvae of aquatic species. It can dissolve protective mucus layers on fish, making them more vulnerable to diseases and parasites. Additionally, it can leach toxic metals like aluminum from the soil into water. High levels of aluminum are toxic to many aquatic organisms, affecting their growth, reproduction, and survival.

Answer:

Acid rain is harmful to aquatic organisms because it lowers the pH of water bodies. This can disrupt the physiological processes of aquatic life. For instance, it can dissolve the protective mucus layers on fish, making them more prone to diseases and parasites. Also, it can leach toxic metals (like aluminum) from the soil into water. High aluminum levels are toxic to many aquatic organisms, affecting their growth, reproduction, and survival. Another aspect is that it can affect the ability of fish to take in oxygen through their gills and can harm the eggs and larvae of aquatic species as they have specific pH requirements for development.
