Multiple choice commercial applications sources of water conservation of natural and energy resources energy conservation and sources importance of the conservation of natural resources reduce, recycle, reuse

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

  1. Prevent precipitation

  2. Stop the water cycle

  3. Make oxygen molecules unavailable to aquatic life

  4. Make nitrates unavailable to aquatic life
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

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.

Biogas generation is mainly based on the principle of

  1. Fermentation

  2. Degradation

  3. Putrification

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Biogas is a flammable gas that is produced from the fermentation or degradation of biomass in biogas plants. Biogas typically refers to a gas produced by the biological breakdown (degradation) of organic matter in the absence of oxygen. whereas the breakdown of organic matter, usually by bacterial action, resulting in the formation of other substances of less complex constitution with the evolution of ammonia is known as putrification.
