World wild life week is

  1. First week of September

  2. First week of October

  3. Third week of October

  4. Last week of October


Correct Option: B
Explanation:

World wild life week is celebrated on October - 2nd to 8th. It is celebrated to  protect the fauna. It was started in 1952 with some major steps in order to protect the Indian wild life  and enrich the diversity in the fauna. Indian Board of Wild Life was a regulatory body set up by the Indian government to spread awareness for wild life preservation.


Wildlife conservation means the protection and preservation of

  1. Ferocious wild animals only

  2. Wild plants only

  3. Non-cultivated plants and non-domesticated animals

  4. All the above living in natural habitat


Correct Option: D
Explanation:
Wildlife conservation is the strategy to protect wild plant and animal species and their habitats. The goal of wildlife conservation is to ensure that nature will be maintained for next generations and also to recognise the importance of wildlife
So, the correct answer is 'All the above living in natural habitat'

Evil quartet is related to

  1. Loss of biodiversity

  2. Loss of alien species

  3. Loss of standing crop

  4. Loss of climax community


Correct Option: A
Explanation:
Jarod Diamond in 1984 listed four principal mechanisms for the loss of biodiversity. It was known as the 'Evil quartet'. It was also known as ‘four horsemen of the ecological apocalypse. The four mechanisms were:-
a) overhunting (or overexploitation),
b) introduced species,
c) habitat destruction and
d) chains of linked extinctions (trophic cascades, or co-extinctions).
So, the correct answer is 'Loss of biodiversity'.

Extinction is caused by ............

  1. Deforestation

  2. Over-exploitation of animals

  3. The destruction of aquatic habitats by pollution

  4. All of the above


Correct Option: D
Explanation:

Extinction means a group of species, family or larger group that have no living member. The extinction can be caused due to various factors such as deforestation (cutting down of trees), Over exploitation of organisms for human good, or by the destruction of the natural habitat or organism. 

So, the correct answer is 'All of the above'.

All of the following are included in 'Ex-situ conservation' except.

  1. Wildlife safari parks

  2. Sacred groves

  3. Botanical gardens

  4. Seed banks


Correct Option: A
Explanation:

Ex-situ conservation is the conservation and maintenance of samples of living organisms outside their natural habitat, in the form of whole plants, seed, pollen, vegetative propagules, tissue or cell cultures. These ex situ collections of living organisms (living collections, seed banks, pollen, vegetative propagules, tissue or cell cultures) need to be managed according to strict scientific and horticultural standards to maximize their value for conservation purposes. Thus they need to be correctly identified, documented and managed and an efficient information management system put in place. Integrated conservation management can also ensure that ex situ collections can support in situ conservation, through habitat restoration and species recovery. 

So the correct option is 'Wildlife safari parks'.

Which of the following are related to the board utilization arguments of conserving biodiversity?

  1. Plants as the source of medicines

  2. Trees used for firewood

  3. Pollination in plants

  4. It is the source of industrial products


Correct Option: A

Organism living in cold areas have shorter extremities than the organisms of warm area. It states

  1. Graubaer's law

  2. Dollo's law

  3. Allen's law

  4. Bergman's law


Correct Option: C
Explanation:

The climatic conditions in a particular area regulate the  physiological and the morphological characteristics of plants or animals. Allen's rule is a biological rule by Joel Asaph Allen in 1877. It states that the organism adjusts in the given climatic conditions by either minimizing exposed surface area to minimize heat loss in cold climates or maximizing exposed surface area to maximize heat loss in hot climates. The rule predicts that endotherms from hot climates usually have ears, tails, limbs, snouts, etc that are long and thin, while equivalent animals from cold climates usually have shorter and thicker versions of those body parts. 

Allen's rule predicts that endothermic animals with the same body volume should have different surface areas that will either aid or impede their heat dissipation.

The protection of animal species is important, because they are 

  1. Lovely creatures

  2. Useful to humans as part of ecosystem

  3. To be studied by zoologists

  4. None of the above


Correct Option: B
Explanation:

Protection of animal species is important, because they are useful for humans as a part of ecosystem. They play a significant role in food web also. Wildlife conservation is the practice of protecting wild plant and animal species and their habitats. Among the goals of wildlife conservation are to ensure that nature will be around for future generations to enjoy and to recognize the importance of wildlife and wilderness lands to humans. Wildlife conservation has become an increasingly important practice due to the negative effects of human activity on wildlife. Thus, the correct answer is option B.

Wild Life of nature is renamed as

  1. World Wild Life conservation of nature

  2. World Wild Life of nature

  3. World Wild Fauna

  4. World Wild Life Fund


Correct Option: D
Explanation:

The wildlife is a valuable resource of our country which needs to be protected from the threats imposed by human activities. Several regulatory bodies have laid certain formulations to protect them. The 'World Wide Fund for Nature' (WWF)  deals with the issues regarding the conservation, research, and restoration of the environment. It is an international non-governmental organization founded on April 29, 1961, and isIt was formerly named the 'World Wildlife Fund', which remains its official name in Canada and the United States. It is the world's largest conservation organization with over 5 million supporters worldwide, working in more than 100 countries, supporting around 1,300 conservation and environmental projects.
