\$\textbf{Correct option:}\$ (C)\$\textbf{Explanation for correct option:}\$\$\bullet\$ The accelerated rates of species extinction which the world is facing are mainly due to human activities.\$\bullet\$ There are four major causes of loss of biodiversity ("The Evil Quartet)":i) Habitat loss and fragmentationii) Over exploitation of natural resources iii) Alien species invasionsiv) Co- extinctions\$\bullet\$ Zoological parks are the means of ex situ conservation of biodiversity in which animals are taken out from their natural habitat and placed in special setting where they are protected and given proper care.\$\bullet\$ Hence, the correct option is (C)

Question 1

Which of the following is not an ex-situ conservation?

Accepted Answer

In situ conservation is the production and management of important components of biological diversity through a network of protected areas. This can be wildlife sanctuaries, national parks, biosphere reserves etc.Ex situ conservation is the conservation of selected rare plants or animals in places outside the natural forms.Ex-situ conservation includes off-site collection and gene banks. Ex situ conservation is conserving the animals and plant outside the natural habitat. Ex situ conservation includes offsite collection and gene banks.Offsite collections are the live collection of file and domesticated species in the botanical garden.Gene bank is an institution where available plant material is preserved in a viable condition.Seed Bank stores seed in the viable stateZoos or zoological parks are places where animals are kept in captivity and bred.So, the correct option is 'Biosphere reserve'

Question 2

An example of ex situ conservation is

Accepted Answer

Conservation of biodiversity is of two types, Ex Situ conservation and In Situ conservation1. Ex Situ conservation means conservation outside the habitats by perpetuating sample population in genetic resource centres, for example, zoos, botanical gardens etc. or in the form of gene pools and gamete storage, germplasm banks for seeds, pollen etc.2. In Situ conservation is the conservation of living resources through their maintenance within the natural ecosystems in which they occur. For example, national parks, sanctuaries, natural reserves, biosphere reserves, sacred grooves etc.Hence, Seed Bank is an example of Ex Situ conservation.So, the correct answer is 'Seed bank'.

Question 3

Which one of the following is an example of ex situ conservation?

Accepted Answer

Ex-situ conservation is the preservation of samples of biological origin outside their natural habitats. This involves conservation of genetic resources as well as wild and cultivated species. A seed bank stores seeds as a source for planting in case seed reserves elsewhere are destroyed. It is a type of gene bank. The seeds stored may be food crops or those of rare species to protect biodiversity. Whereas in-situ conservation is the conservation and maintenance of samples of living organisms in their natural habitat. Wild life sanctuary, sacred groves and national park are examples of in-situ conservation. Thus, the correct answer is option B.

Question 4

Which one of the following is not included under in-situ conservation?

Accepted Answer

In-situ conservation is on-site conservation or the conservation of genetic resources in natural populations of plant or animal species. It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or cleaning up the habitat itself, or by defending the species from preadtors. Around 4% of the total geographical area of the country is used for in-situ conservation. The following methods are presently used for in-situ conservation is biosphere reserves, national parks and wild life sanctuaries. Botanical gardens are included under Ex-situ conservation.

Question 5

Which of the following are not in-situ conservation?$1$. Zoological Park$2$. Sanctuaries$3$. Botanical garden$4$. National ParkSelect the correct answer using the codes given.

Accepted Answer

In-situ conservation is the on-site conservation or the conservation of genetic resources in natural populations of plant or animal species. It is the process of protecting an endangered plant or animal species in its natural habitat, either by protecting or restoring the habitat itself or by defending the species from predators. Examples - Sanctuaries and National Parks.Ex situ conservation literally means, &#34;off-site conservation&#34;. It is the process of protecting an endangered species, variety or breed, of plant or animal outside of its natural habitat; for example, by removing part of the population from a threatened habitat and placing it in a new location, which may be a wild area or within the care of humans.  Examples - Zoological Park and Botanical Garden.So the correct option is '1 and 3'.

Question 6

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

Accepted Answer

The narrowly utilitarian arguments for conserving biodiversity areobvious; humans derive countless direct economic benefits from nature food (cereals, pulses, fruits), firewood, fibre, construction material,industrial products (tannins, lubricants, dyes, resins, perfumes ) andproducts of medicinal importance. More than 25 per cent of the drugscurrently sold in the market worldwide are derived from plants and 25,000species of plants contribute to the traditional medicines used by nativepeoples around the world. Nobody knows how many more medicinallyuseful plants there are in tropical rain forests waiting to be explored.With increasing resources put into &#8216;bioprospecting&#8217; (exploring molecular,genetic and species-level diversity for products of economic importance),nations endowed with rich biodiversity can expect to reap enormousbenefits.So the correct option is '(i), (iv) and (vi)'.

Question 7

Which of the following is not a cause for loss of biodiversity?

Accepted Answer

$\textbf{Correct&#10;option:}$ (C)$\textbf{Explanation for correct option:}$$\bullet$ The accelerated rates of species extinction which the world is facing are mainly due to human activities.$\bullet$ There are four major causes of loss of biodiversity (&#34;The Evil Quartet)&#34;:i) Habitat loss and fragmentationii) Over exploitation of natural resources iii) Alien species invasionsiv) Co- extinctions$\bullet$ Zoological parks are the means of ex situ conservation of biodiversity in which animals are taken out from their natural habitat and placed in special setting where they are protected and given proper care.$\bullet$ Hence, the correct option is (C)

Question 8

Botanical gardens and zoological parks have.

Accepted Answer

Botanical gardens and zoological parks are specialised places where living plants are grown and living animals are kept (where they can reproduce too) respectively. Both, endemic (local) as well as exotic (foreign to that place) species are kept in these places. They can be used for scientific studies. Botanical garden at Kew, England and National Zoological Park, Delhi are some famous examples.

Question 9

What are sacred groves? Mention any two examples.

Accepted Answer

The sacred grooves are the trees which are considered as socially, culturally, medicinally or religiously important. The common examples of sacred grooves are Ficus Religiosa (Peepal) tree and Ficus benghalensis (Banyan) tree. Tese trees are considered as religiously important due to their huge production of oxygen and helping in maintaining the balance in the atmosphere.

Question 10

Loss of biodiversity in a region may lead to _________________.

Accepted Answer

C) Increased variability in plant productivity loss of biodiversity in a region may lead to @ decline in plant production (b) Loweredresistance to environmental perturbationssuch as drough (c) increase variability in certain ecosystem process such as plantproductivity, water use, and pest and disease cycles.
