D Correct answer
Explanation

Keystone species are those species which have significant and disproportionately large influence on the community structure and characteristic. It has often considered low abundance and biomass as compared to dominant species.

Biodiversity can be conserved by developing ................ and

  1. Hotspots and oceans

  2. Forest and hotspots

  3. Sanctuary and oceans

  4. Biosphere reserve and National park
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Biodiversity can be conserved by developing Biosphere reserve and National park.
A biosphere reserve can be defined as a protected land or area to conserve the biological and cultural diversity of a region while promoting sustainable economic development. 
A national park is an area reserved for wildlife where they can freely use the habitat and natural resources. Thus, the correct answer is option D.

The knowledge of which of the following factors does not help in the management of endangered animal?

  1. Habitat of the animal

  2. Behavior of the animal

  3. Food habit of the animal

  4. Name of the animal
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Understanding an animal's habitat, behavior, and food habits is essential for conservation and management. The name of the animal is merely a label and does not provide biological or ecological insight required for management.

Conservation of resources can be tackled through _____.

  1. Human population control

  2. Reducing pollution

  3. Increasing use of resources

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

Conservation of resources is nothing but using resources optimally to prevent its exhaustion completely from the universe. It can be achieved by stopping misuse of resources. Resources can also be conserved by human population control, reducing pollution.

One of the ex-situ conservation methods for endangered species is

  1. Wildlife sanctuaries

  2. Biosphere reserves

  3. Cryopreservation

  4. National parks
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ex-situ conservation is the preservation of components of biological diversity outside their natural habitats. Cryopreservation is the only option here where the species are preserved at very low temperature to preserve structurally intact living cells and tissues.

Multiple choice evs earth - our home need to conserve biodiversity protecting our environment rules are for everyone

'Broadly utilitarian' argument for the conservation of biodiversity does not include

  1. Bioprospecting

  2. Pollination

  3. Aesthetic value

  4. Climatic regulation
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Bioprospecting is the exploration of molecular, genetic and species level-diversity for gaining the products of economic importance. It comes under narrowly utilitarian category. 

Multiple choice evs earth - our home need to conserve biodiversity protecting our environment rules are for everyone

The narrowly utilitarian arguments for biodiversity conservation include which of the following from the given list?
(i) Industrial products like dyes, lubricants
(ii) Ecosystem services like photosynthesis
(iii) Pollinators layer of bees, birds and bats
(iv) Firewood, fibre and construction material 
(v) The aesthetic pleasure of walking through thick woods 
(vi) Products of medicinal importance
(vii) Watching spring flowers in full bloom

  1. (i), (ii), (v) and (vii)

  2. (ii), (iii), (v) and (vii)

  3. (i), (iv) and (vi)

  4. (iii), (v), (vi) and (vii)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation
The narrowly utilitarian arguments for conserving biodiversity are
obvious; humans derive countless direct economic benefits from nature food (cereals, pulses, fruits), firewood, fibre, construction material,
industrial products (tannins, lubricants, dyes, resins, perfumes ) and
products of medicinal importance. More than 25 per cent of the drugs
currently sold in the market worldwide are derived from plants and 25,000
species of plants contribute to the traditional medicines used by native
peoples around the world. Nobody knows how many more medicinally
useful plants there are in tropical rain forests waiting to be explored.
With increasing resources put into ‘bioprospecting’ (exploring molecular,
genetic and species-level diversity for products of economic importance),
nations endowed with rich biodiversity can expect to reap enormous
benefits.
So the correct option is '(i), (iv) and (vi)'.
Multiple choice evs earth - our home need to conserve biodiversity protecting our environment rules are for everyone

Which of the following is true about conservation and preservation?
I. Protects the ecosystem from destruction
II. Prevents the depletion of natural resources.
III. Maintains the population of endangered plants and animal species.

  1. I only

  2. I and II only

  3. II and III only

  4. I, II and III
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation
Conservation is the sustainable use and management of natural resources, both renewable and non-renewable. Preservation is the strict keeping aside of natural resources so as to prevent the use or contact of resources by humans or by human intervention. 
Conservation ensures that resources are not consumed faster than they can be replaced. It also ensures that  sufficient quantities are maintained for future generations to utilise. Thus, it is involved in preventing the depletion of natural resources. The main purpose of conservation and preservation is to protect the ecosystem from destruction due to increased use of or consumption of resources. Conservation is also carried out to protect plant and animal species from being extinct. It maintains the population of endangered species by protecting and restoring the habitats and maintaining the essential ecological processes and life-support systems. 
Thus, the correct answer is option D.

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
Reveal answer Fill a bubble to check yourself
D Correct answer
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'
Multiple choice evs earth - our home need to conserve biodiversity protecting our environment rules are for everyone

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
Reveal answer Fill a bubble to check yourself
B Correct answer
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.

Multiple choice evs earth - our home need to conserve biodiversity protecting our environment rules are for everyone

What are the control methods that are to be adopted to restore balance in the ecosystems?

  1. Rain water harvesting for conservation and management of water.

  2. Conservation of ocean resources and preservation of marine life.

  3. Public awareness programmes concerning conservation of wildlife.

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

We know that the level of the ground is decreasing day by day due to its excessive use. As a result, the world is facing serious water issues. Apart from this, oceans form a resource for the development of electricity from water and form a habitat for a vast variety of marine organisms. Marine organisms form a major part of biodiversity fauna. All these are natural resources necessary to maintain the balance of the ecosystem.

So, option D "All of these"is the correct answer.
