1.	Write any two ways by which water pollution affect the aquatic organism.
Answer» Organic matter and nutrients cause an increase in aerobic algae and deplete oxygen from the\xa0water\xa0column. This causes the suffocation of fish and other\xa0aquatic organisms. Sulfate particles from acid rain can cause harm to the health of\xa0marine\xa0life in the rivers and lakes it contaminates and can result in mortality.\xa0A lack of sufficient oxygen kills off aquatic life and plants, resulting in dead zones and threatening the survival of the ecosystem. Land\xa0animals, birds, and humans can also be harmed by the contaminated\xa0water, or by consuming fish or shellfish that lived in contaminated\xa0water.
