A Correct answer
Explanation

Wetlands are areas of land where the water level remains near or above the surface of the ground for most of the year. India has a wealth of wetland ecosystems distributed in different geographical regions. Wetland systems, directly and indirectly, support lakhs of people, providing goods and services to them. They help check floods, prevent coastal erosion and mitigate the effects of natural disasters like cyclones and tidal waves. They store water for long periods. The scheme on conservation and management of wetlands was initiated by the Ministry of Environment, Forest and Climate Change (MoEF&CC) in $1987$ with the following objectives:


  1. To lay down policy guidelines for conservation and management of wetlands in the country;
  2. To undertake intensive conservation measures in priority wetlands;
  3. To monitor the implementation of the programme; and
  4. To prepare an inventory of Indian wetlands.

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.

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.

  3. They protect different ecosystems

  4. They protect all types of flora
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

National parks are designated areas that protect entire ecosystems, including the flora, fauna, and physical environment, ensuring the preservation of biodiversity.

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'.

Multiple choice commercial studies forest : our life conservation of forest and wildlife wildlife forest - the dwelling place of animals deforestation and conservation

Forest conservation is the practice of 

  1. Inheritance of characters from parents

  2. Protection of forest areas

  3. Preservation of food

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

Forest conservation is the practice of planning and conserving forest areas for the benefit of future generations. Afforestation is the establishment of a forest in an area either naturally or artificially where there was no forest previously. It is done to keep the natural resources intact for the maintenance of ecosystem and benefit of human. Different techniques done for forest conservation are afforestation, reforestation, controlled burn, etc. 

Thus, the correct answer is option B.

Multiple choice commercial studies striving for a better environment soil and its conservations soil pollution-control protecting our environment

For better survival of human population, which is the most important step?

  1. Afforestation

  2. Reduction in population density

  3. Conservation of wild life including tribals

  4. Both A and B
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Afforestation refers to the conversion of wasteland into a woodland or forest. It is essentially the transformation of land which has not been forested for a period of more than 40 year to woodland through seeding and planting. Afforestation is the best technique used to minimize the greenhouse effect. Planting of trees in semi-arid areas attracts rainfall. This way, agricultural practices such as irrigation are carried out efficiently. In addition, afforestation acts as a catchment for water and soil conservation. With an increase in demand for forest and timber products, afforestation is very valuable due to the explosion of livestock and human population. Disadvantages of high human population density are global warming, pollution, rapid use of natural resources, more exploitation of other living forms and non living systems like rivers, faster destruction of natural systems, deforestation, habitat destruction, pollution, extinctions etc. Hence population density should be reduced. 

Therefore, the correct answer is option D.
