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.

Effect of pollution is first marked on 

  1. Micro-organisms

  2. Green vegetation of an area

  3. Food crop

  4. None of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Atmospheric pollutants have a negative effect on the plants; they can have direct toxic effects, or indirectly by changing soil pH followed by solubilization of toxic salts of metals like aluminium. The particulate matters have a negative mechanical effect. They cover the leaf blade reducing light penetration and blocking the opening of stomata. These influence strongly the process of photosynthesis whose rate declines sharply. Also, the leaves of the trees have an important role in the retention of the particulate matters; they are mostly affected when the wet and dry atmospheric deposition increase.

So, the correct answer is option B.

Pollutants in form of fine dust particles are known as

  1. Dry Deposits

  2. Wet Deposits

  3. Rain

  4. Snow
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dry deposition refers to the process where fine dust particles, aerosols, and gases settle out of the atmosphere onto surfaces without the presence of precipitation.

Any unfavorable alteration of the environment may be called as

  1. eutrophication

  2. environmental pollution

  3. biomagnigication

  4. bioaccumulation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Environmental pollution is defined as the introduction of harmful materials or unfavorable alterations into the environment that cause adverse effects on living organisms.

During inversion, visibility is reduced and pollutant concentration is

  1. Minimized

  2. Maximized

  3. Reduced

  4. Decreased
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Temperature inversion traps pollutants near the ground by preventing vertical mixing, which leads to a buildup and maximization of pollutant concentrations in the lower atmosphere.
