Effect of pollution is first and most marked on

  1. Natural flora of a place

  2. Natural geochemical cycle

  3. Natural gaseous cycle

  4. Natural balance of our environment
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Green plants are the producers through which inorganic elements first enter the food chain. Green plants take in elements from the atmosphere, soil and water and manufacture food on which all the other animals either directly or indirectly feed on. Since plants are directly exposed to pollutants, the effect of pollution is first visible in natural flora of a place, then it will be visible on organisms that are dependent on the plants.

Effect of pollution is on

  1. Crossing over

  2. Ecological balance

  3. Linkage

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

Pollution is any change in physical, chemical, or biological characteristics of the environment, that has the potentiality to harm human life, life of other desirable species, natural resources, cultural assets and industries. Pollution affects the atmosphere, hydrosphere and lithosphere by disturbing the delicate balance between abiotic and biotic components and the interaction between various organisms. Thus, the correct answer is option B.

How environmental pollution can be controlled?

  1. Least use of fossil fuel

  2. The effluent of factories should be treated before discharge into surrounding environment

  3. By using more biodegradable products

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
  • Environmental pollution is the release of chemical waste that causes detrimental (causing harm) effects on the environment. Environmental pollution is often divided into water pollution, air pollution, and soil pollution.
  • Environmental pollution can be controlled by Least use of fossil fuel, The effluent of factories should be treated before discharge into the surrounding environment and By using more biodegradable products.
  • So, the correct answer is 'All the above'.

Which statement is wrong about pollution?

  1. Leaded petrol is used in vehicle that has catalytic converter

  2. Hot water releases from thermal power plants

  3. Presence of DDT in food chain

  4. Biological control does not create pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Leaded petrol poisons the catalyst in a catalytic converter, rendering it ineffective. Therefore, leaded petrol should not be used in vehicles equipped with catalytic converters.

Spraying of DDT on crops produces pollution of 

  1. Soil and water only

  2. Air and soil only

  3. Air, soil and water

  4. Air and water only
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Large amounts of DDT are released into the air and on soil or water, when sprayed on crops and forests to control mosquitoes and other insects. Also, DDT may enter the atmosphere when it is evaporated from contaminated water and soil. DDT in the air may then be deposited on land or surface waters. This cycle of evaporation and deposition may be repeated many times. As a result, DDT causes an undesirable change in the atmosphere.
