  1. Natural geochemical cycles

  2. The natural balance of our environment

  3. The natural flora of our environment

  4. The natural wild life of our region

Show answer
Correct Option: B
Explanation:

The environment is our surrounding. This includes living and non-living things around us. The non-living components of the environment are land, water and air. The living components are plants and animals. All plants and animals adjust to the environment in which they are born and live. A change in any component of the environment may cause discomfort and affect normal life. Any unfavourable change or degradation in the environment is known as environmental pollution. Thus, the correct answer is option B.

  1. Typhoid

  2. Minamata disease

  3. Syphilis

  4. Goiter

Show answer
Correct Option: B
Explanation:

The best known example of heavy metal pollution in the oceans took place when Japanese factory discharged a significant amount of mercury metal into Minamata Bay, contaminating the fish stocks there. By that time, many local people had eaten the fish and around 2000 were poisoned. Hundreds of people were left dead or disabled.

Read the passage and answer the following questions:
Six pairs of bald vulture were released into the wild in Germany. Four of the pairs of birds successfully nested and raised young. Two of the pairs nested near an industrial complex that released waste products (PCBs) into a nearby lake. These birds laid eggs, but the embryos failed to develop.
Which of the following is the least likely reason for the failure of the embryos to develop?

  1. Mutations in the embryos halted their development.

  2. The adult birds failed to exhibit proper nesting behavior and did not care for the eggs.

  3. The contaminated lake water that the birds consumed affected the development of their young.

  4. The sperm of the males were affected by the PCBs in such a way that they were unable to fertilize the eggs.

  5. Germany is not a good location for bald eagles to mate and reproduce.

Show answer
Correct Option: E
Explanation:

The release of waste products into the nearby lake caused various problems which led to the failure of the embryo development. This can happen because of the following reasons:

  • The chemicals released from the factory caused some mutations in the embryos which led to the failure in development.
  • The birds might not have taken care of the eggs and they might have failed to exhibit proper nesting behavior.
  • The chemicals in the contaminated lake water might have affected the development of the birds.
  • The chemicals from the lake might have affected the sperms of the males and so they were unable to fertilize the eggs. Thus, the correct answer is option E.

For clean environment, which one is not essential?

business organisation and correspondence industrial pollution and degradation of environment sources of pollution environmental conservation environment and conservation

  1. Producer

  2. Polluter

  3. Consumer

  4. Decomposer

Show answer
Correct Option: B
Explanation:

The producer is required initially for the availability of organic food. The consumer will consume the organic food prepared by the producer and will also make an equilibrium in the environment by being a part of the nutrient cycle. A decomposer will breakdown the dead organic from the dead bodies of producer and consumer. So, these are required in a functional ecosystem. The presence of polluter is undesirable as it would distort the environment, making it difficult for the biotic and abiotic components to keep their sustenance.

Hence, the correct answer is 'Polluter'.

Which of the following statements are correct ?


(I) Benzene hexachloride (BHC) is a non-biodegradable pollutant.
(ii) Anthropogenic air pollutants are natural in origin.
(iii) Carbon monoxide is a primary air pollutant.
(iv) Sulphur dioxide causes brown air effect during traffic congestion in cities.

  1. (i) and (iii)

  2. (i) and (ii)

  3. (ii) and (iii)`

  4. (ii) and (iv)

Show answer
Correct Option: A
Explanation:

Anthropogenic air pollutants are man-made pollutants like emissions, burning of fossil fuels, mining, etc. Sulpur dioxide is produced in large quantities during the smelting of metallic ores and the burning of petroleum and coal in industries and by motor vehicles. It is cause of acid rain

  1. Water pollution

  2. Noise pollution

  3. Land pollution

  4. Air pollution

Show answer
Correct Option: D
Explanation:

Carbon monoxide is the colorless, odorless and tasteless gas that is slightly less dense than air. It is emitted by vehicles. It mixes with the air and causes air pollution on a large scale. Carbon monoxide is released through emissions through automobiles, thermal power plants,etc.
