What influences oxygen levels in the water?
A) Sewage run-off has little adverse effect on oxygen levels.
B) Inorganic nutrients such as fertilizers increase oxygen levels.
C) Organic wastes reduce the amount of oxygen in the water supply.
D) Heat can increase dissolved oxygen and make fish less vulnerable to disease.
Organic Wastes
Biological materials originating from living organisms that are capable of being decomposed by other living organisms.
Oxygen Levels
The amount of oxygen present in a given environment or substance, often measured to assess air or water quality.
Inorganic Nutrients
Nutrients that do not contain carbon-hydrogen bonds, essential for plant growth, such as nitrogen, phosphorus, and potassium.

Final Answer :
C
Explanation :
Organic wastes, such as from animal waste or decaying plant matter, consume oxygen as they decompose, leading to a decrease in oxygen levels in the water. This can create uninhabitable conditions for aquatic life. Sewage run-off and inorganic nutrients, on the other hand, can contribute to eutrophication and algal blooms, which can also reduce oxygen levels but in a different way. Heat can increase the amount of dissolved oxygen in the water, but it is not a reliable or effective method of improving water quality.
