C Correct answer
Explanation

Biodiversity is the variety of different types of life found on the Earth and the variations within species. It is a measure of the variety of organisms present in different ecosystems. we must preserve it as we have inherited it and maintain the ecological stability.

Restoration of ecological equilibrium in mined areas can be achieved through

  1. Revegetation of the mined habitats

  2. Conversion of mined habitats into agricultural ecosystems

  3. Prevention of soil erosion

  4. Prevention of grazing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A number of world's ecosystems have undergone significant degradation leading to a negative impact on the biodiversity and livelihood. One such ecosystem that has depleted over the years is the mined habitats. Since the mineral rich areas are also rich in forest resources. However continuous mining activities tend to change the ecological equilibrium. Restoration of the ecological equilibrium of the mined areas can be achieved by understanding the ecology, plant succession and soil types of the place and revegetation of the spoils .

Animals species should be preserved mainly because

  1. They are lovely creatures.

  2. They are useful to mankind.

  3. Man cannot recreate a species of animals if it be destroyed.

  4. Zoologists want to study them.
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

There are many reasons to conserve biodiversity, but all equally important. They can be grouped into three categories: narrowly utilitarian (economic benefit), broadly utilitarian (importance in natural ecological balance), and ethical (moral reasons). 

All the animals are a part of biodiversity, hence need to be conserved. 
Man makes special efforts to conserve the animals which are likely to become extinct without special efforts of man. In fact man makes an effort to conserve biodiversity and animals are a part of biodiversity. 
Once a species becomes extinct the entire gene pool is lost for ever. This is also called as genetic erosion.

Which of the following will help most in conservation of wildlife?

  1. Making stringent laws

  2. Making numerous zoos

  3. Making numerous sanctuaries

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

A naturally occurring sanctuary, such as an island, which protects species from getting hunted, predated or poached is called as a wildlife refuge. It is also known as a wildlife sanctuary. Being a protected area, it is a geographic territory within which wildlife is protected. Private operations are limited in such areas. Thus, making numerous wildlife sanctuaries will be most helpful.

So, the correct answer is 'Making numerous sanctuaries'.

Wildlife conservation and soil conservation are closely related.

  1. True

  2. False
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation
Wildlife conservation, forest conservation and soil conservation are greatly related as wildlife depend on forests because forests are only home and shelter for them so wildlife would be conserved if forests conservation is done. If any animals die its humus helps the plant to grow because it gives so many minerals and many animals help in germination of seeds. Then forests would be conserved if wildlife conservation is done. Then plant's roots hold the soil and soil degradation is greatly reduced which is done due to forests conservation. And we know it takes million years to form soil. So wildlife conservation, soil conservation and forest conservation are closely related. Each of them are interdependent.
So, the correct answer is 'True'.

Which of the following helps to preserve the biosphere for future generations?

  1. Make use of technology to develop new herbicides

  2. Put all wild animals in game preserves

  3. Explore ways to drain and fill wetlands along the seacoast

  4. Understand how living things interact with their environment

  5. Settle more people inland, away from the coasts
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The biosphere can be defined as a global ecological system that integrates all living beings and their relationships with other elements of the lithosphere, geosphere, hydrosphere and atmosphere. To preserve the biosphere for future generations, one needs to understand the livings things present and how they interact with their environment and the extent to with they are interdependent.

So, the correct option is D.

Various forms of life should be conserved as they

  1. Will be lost otherwise

  2. Have economic values

  3. Contain diverse genetic resources

  4. Are important for maintaining balance of nature
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biodiversity includes the enormous diversity of flora and fauna in the world. A great threat to it is now possessed by the increased rates of destructive activities. Various methods are being adopted by the authorities to conserve the species richness at various levels. If any species gets extinct, the gene pool of that species will be lost. So, the need for conservation of species is to conserve the different genetic resources.

So, the correct answer is 'Contain diverse genetic resources'.

Which of these programmes is used to conserve a species from extinction?

  1. Captive breeding

  2. Natural resources

  3. Sustainable use

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

Captive breeding is the process of maintaining plants or animals in controlled environments, such as wildlife reserves, zoos, botanic gardens, and other conservation facilities. It is sometimes employed to help species that are being threatened by human activities. The activities which pose threat include habitat loss, fragmentation, over-hunting or fishing, pollution, predation, disease, and parasitism. The objective of many captive populations is to hold similar levels of genetic diversity to what is found in wild populations.

So, the correct answer is 'Captive breeding'.
