Which of the following country is responsible for releasing largest amount of green-house gases?

  1. Russia

  2. Germany

  3. Brazil

  4. America (USA)
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Greenhouse gases trap heat and make the planet warmer causes global warming. Human activities are responsible for almost all of the increase in greenhouse gases in the atmosphere over the last 150 years and USA is responsible for releasing largest amount of greenhouse gases. The primary sources of greenhouse gases in USA are electricity production (31%), transportation (27%), industry (21%), commercial and residential (12%) etc.

Therefore, the correct answer is option D.

A pollutant is an agent which causes change in

  1. Balance of nature

  2. Local flora

  3. Geochemical cycles

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Geochemical cycle refers to the chemical interactions in surface reservoirs such as the atmosphere, hydrosphere, lithosphere, and biosphere. Pollution is any undesirable change in physical, chemical or biological characteristics of air, land, water or soil. Agents that bring about such an undesirable change are called as pollutants. Local flora and fauna is also affected by the pollutant. Balance of nature also gets disturbed as pollutant affects the living organism and composition of gases in the atmosphere.

A substance that pollute something is called as 

  1. Sewage

  2. Particulate

  3. Pollutant

  4. Smog
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Pollutant is a substance which when introduced into the environment has undesired effects. Pollutant causes long- or short-term damage by changing the environmental factors. Some pollutants are biodegradable and therefore do not persist in the environment in the long term. However, the degradation products of some pollutants are themselves polluting such as the products DDE and DDD produced from degradation of DDT.

Introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e, physical systems or living organisms, is called as

  1. Adulteration

  2. Fortification

  3. Pollution

  4. Enrichment
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
  • Pollution is the introduction of contaminants into the natural environment that causes adverse change. 
  • Pollution can take the form of chemical substances or energy, such as noise, heat or light. Pollutants, the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. 
  • Hence, Introduction of contaminants into an environment that causes instability, disorder, harm or discomfort to the ecosystem i.e, physical systems or living organisms, is called Pollution.
  • So, the correct answer is 'Pollution'.

Which ecosystem generate wealth as well as causes pollution?

  1. Man subsidized solar power ecosystem

  2. Unsubsidized natural solar powered ecosystem

  3. Naturally subsidized solar powered ecosystem

  4. Fuel power ecosystem
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fuel-powered ecosystems (industrialized systems) rely on fossil fuels, which generate significant economic output but are also the primary source of environmental pollution.

The pollutant which effects more to the organism of higher trophic level is  

  1. biodegradable sewage

  2. heavy metal salts and non biodegradable phenolic compounds
  3. $C{O _2}$
  4. $S{O _2}$
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Non- biodegradable compounds such as DDT and mercury accumulate in the tissues of organisms that consume them since they do not break down easily. As a result, when they, in turn, are consumed by secondary organisms their amount magnifies. This is known as biomagnification. Hence, such non-biodegradable compounds affect the organisms of higher trophic level more. So, the correct option is 'heavy metal salts and non-biodegradable phenolic compounds'.

Which is not a positive pollution -

  1. More use of bio fertilizer

  2. Land filling by wastes

  3. Deforestation

  4. Deforestation of nuclear waste in soil
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
Deforestation is a permanent destruction of forests in order to make the land available for other uses and resulting in damage to the quality of land. It leads to loss of many animal and plant species by disturbing their habitat that may result in their extinction.
So the correct answer is 'Deforestation'.

Soap and detergents are the source of organic pollutants like:

  1. Glycerol

  2. Polyphosphates

  3. Sulphonated hydrocarbons

  4. All of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Detergents often contain phosphates (which cause eutrophication), surfactants like sulphonated hydrocarbons, and other organic additives, all of which contribute to water pollution.
