evs sources of water water as nutrient basics of water pollution nutrients and deficiency

  1. 19%

  2. 11%

  3. 7%

  4. 1.1%

Show answer
Correct Option: D
Explanation:
  • Drinking water, also known as potable water, is water that is safe to drink or to use for food preparation.
  • The amount of drinking water required to maintain good health varies, and depends on physical activity level, age, health-related issues, and environmental conditions.
  • Domestic and municipal supplies of water constitute 1.1%  percentage of total water consumption.
  • So,the correct answer is '1.1%'.

Correct Option: C

Many sewer pipelines connect to form the 

evs sources of water water as nutrient basics of water pollution nutrients and deficiency

  1. Drainage

  2. Wastewater body

  3. Sewerage

  4. All of the above

Show answer
Correct Option: C
Explanation:

Sewerage is the infrastructure that conveys sewage from many sewer pipelines. Drainage is an artificial passageway that carries the waste water from the houses. Sewer pipelines are artificial passageway used to carry the sewage and water water from the drainage system. It then carries the waste water to the municipal sewage system or sewerage.   

Thus, the correct answer is option C.

Potable water is the water which is

  1. Obtained from a river.

  2. Obtained from a lake.

  3. Pure and fit for drinking.

  4. Used only for washing clothes.

Show answer
Correct Option: C
Explanation:

Potable water is a water which is fit for consumption by humans and other animals. It is also called as drinking water, in a reference to its intended use. Water may be naturally potable, as is the case with pristine springs, or it may need to be treated in order to be safe. In either instance, the safety of water is assessed with tests which look for potentially harmful contaminants.

Therefore, the correct answer is option C.

Maximum use of fresh water is in

evs sources of water water as nutrient basics of water pollution nutrients and deficiency

  1. Agriculture

  2. Domestic use

  3. Industry

  4. Pisciculture

Show answer
Correct Option: A
Explanation:

Maximum use of fresh water is in agriculture. About 70% of the total fresh water is used in agriculture. About 20% is used for industrial purpose. About 10% of the fresh water is used for domestic and municipal use.

Thus, the correct answer is 'Agriculture.'

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

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

  1. Prevent precipitation

  2. Stop the water cycle

  3. Make oxygen molecules unavailable to aquatic life

  4. Make nitrates unavailable to aquatic life

Show answer
Correct Option: C
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. 

Which of the following are the ways of conserving and preserving the earth's natural resources?

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

  1. Recycling wastes

  2. Using alternative energy sources

  3. Reducing the wastage of non-renewable natural resources

  4. All of these

Show answer
Correct Option: D
Explanation:

Preservation refers to the measures taken to keep living things in their original balanced state. Conservation refers to the careful and systematic use of natural resources without causing harm and death to living organisms in the environment. Recycling of waste, reducing the use of non-renewable natural resources and alternative source are the measures to maintain the natural resources without harming the resources and environment. Thus, the correct answer is option D.

The management of natural resources should take into

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

  1. A long term perspective

  2. Environmental pollution

  3. Their equitable distribution

  4. A, B, C and safe disposal of wastes

Show answer
Correct Option: D
Explanation:

Natural resource management refers to the management of natural resources such as land, water, soil,  plants and animals, with a particular focus on how management affects the quality of life for both present  and future generations. This includes all the above a,b & c points hence d option is the right answer.

Biogas generation is mainly based on the principle of

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

  1. Fermentation

  2. Degradation

  3. Putrification

  4. Both A and B

Show answer
Correct Option: D
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.
