Question

If water pollution continues at its present rate, it will eventually

• A. Prevent precipitation
• B. Stop the water cycle
• C. Make oxygen molecules unavailable to aquatic life
• D. Make nitrates unavailable to aquatic life

Answer 1

The correct option is C Make oxygen molecules unavailable to aquatic life

Water pollution is the condition in which there is an increase in the concentration of the undesirable compounds in the water resources. The pollutants are the organic compounds. The microbes use up the oxygen which is present in the water bodies for the degradation of the organic matter in the pollutants. This lowers the amount of oxygen which is available for the aquatic plants and animals.

Thus, the correct answer is option C.
