Question 1
1 / -0

An example for in situ biological conservation method is to establish

A
Botanical gardens

B
Seed banks

C
Biosphere reserves

D
Zoos

Solution

In situ conservation is on-site conservation or the conservation of organisms in natural habitats.
A biosphere reserve is an area proposed by its residents, ratified by a national committee, and designated by 'UNESCO's Man and Biosphere (MAB) program', which demonstrates innovative approaches to living and working in harmony with nature.
A biosphere reserve is the large protected area to conserve wildlife and culture of tribals. The zoo is the man-made area to protect the wild animal. The seed bank is the conservation of wild seeds in the artificial area.
Question 2
1 / -0

The diversity of species in the environment sharing same community is called

A
Alpha diversity

B
Beta diversity

C
Gamma diversity

D
Biosphere
Solution
- Alpha diversity refers to the diversity at a local site. Alpha diversity is the richness and evenness of individuals within a habitat unit.
- Beta diversity is the diversity among species at different sites.
- Gamma diversity is the diversity of the entire landscape.
- Biosphere refers to the region of the earth where life exists.
Thus, the correct answer is option A.
Question 3
1 / -0

'Biosphere reserve' is an example of

A
In vivo conservation

B
Ex situ conservation

C
In situ conservation

D
All of the above

Solution

A biosphere reserve is an ecosystem with plants and animals of unusual scientific and natural interest. It is a title given by UNESCO to help protect the sites. The plan is to promote management, research and education in ecosystem conservation. This includes the 'sustainable use of natural resources'.
In situ conservation is on-site conservation or the conservation of genetic resources in natural populations of plant or animal species, such as forest genetic resources in natural populations of tree species.
Question 4
1 / -0

MAB stands for

A
Man, antigens, biology

B
Man and biosphere programme

C
Man and biology

D
Man and biotic community
Solution
- UNESCO's 'Man and the Biosphere Programme' (MAB) is an intergovernmental scientific programme, that aims to establish a scientific basis for the improvement of relationships between people and their environments.
MAB combines the natural and social sciences, economics and education to improve human livelihoods and the equitable sharing of benefits, and to safeguard natural and managed ecosystems.
Question 5
1 / -0

The conservation of local (endemic) varieties of crops is must because

A
These are source of genes for genetic diversity.

B
These are high yielding and nutritious.

C
We want to conserve all plants and animals of the past for our knowledge.

D
All of the above.

Solution

Genetic diversity refers to the variety of genes within a species. Each species is made up of individuals that have their own particular genetic composition. Within a species there may also be discrete populations with distinctive genes. Sexual reproduction is critical for maintaining genetic diversity within a species, because it combines the parents genetic material, resulting in offspring with unique genetic blue prints different from either parent.
The conservation of local varieties are important, as they provide genes for genetic diversity.
Question 6
1 / -0

What is a keystone species?

A
A species which makes up only a small proportion of the total biomass of a community, yet has a huge impact on the community's organization and survival.

B
A common species that has plenty of biomass, yet has a fairly low impact on the community's organization.

C
A rare species that has minimal impact on the biomass and on other species in the community.

D
A dominant species that constitutes a large proportion of the biomass and which affects many other species.

Solution

A keystone species is often a dominant predator whose removal allows a prey population to explode and often decreases overall diversity. Other kinds of keystone species are those, such as coral or beavers, that significantly alter the habitat around them and thus affect large numbers of other organisms.
Question 7
1 / -0

When is the 'World Wild Life Week' observed?

A
First week of September

B
Last week of September

C
Third week of October

D
Last week of October

E
First week of October

Solution

In order to arouse a general awakening in the common man in favour of protection of wildlife, the 'Indian Board of Wild Life' (IBWL) decided to observe the 'Wildlife Week' and since then from October 2 - 8 every year organize different activities related to wildlife conservattion to commemorate this week.
Every year around this time (October 2 to 8) governments, environmentalists, activists, educators organize different activities to accelerate the awareness of wildlife conservation among people.
India, being a mega-storehouse of various species, is also able to manage several conferences, awareness programmes, and public meetings among the nature lovers. Schools and educational institutions organize events such as wildlife related movie screening, painting competition/essay writing/ debate competition for young children with wild life as the theme.
Question 8
1 / -0

The Siberian crane from Russia is a regular visitor to the bird sanctuary in which one of the following place in India?

A
Lallbagh, Bangalore

B
Vendanthgol sanctuary, Tamil Nadu

C
Ranganathittis sanctuary, Karnataka

D
Bharatpur sanctuary, Rajasthan

Solution

One of the finest bird parks in the world, Bharatpur bird sanctuary also known as 'Keoladeo Ghana National Park' is a reserve, that offers protection to faunal species as well.
Nesting indigenous water birds as well as migratory water birds and waterside birds, this sanctuary is also inhabited by sambar, chital, nilgai and boar.
The major attractions of tourists visiting the park are the numerous migratory birds, which come from as far away as Siberia and Central Asia and spend their winters in Bharatpur, before returning to their breeding grounds.
Migratory birds at Bharatpur bird sanctuary include, several species of cranes, pelicans, geese, ducks, eagles, hawks, shanks, stints, wagtails, warblers, wheatears, flycatchers, buntings, larks and pipits, etc.
Question 9
1 / -0

The country which hosted the first World Earth Summit on conservation of environment is

A
India

B
Brazil

C
Peru

D
Spain

Solution

From 3 - 14 June 1992, Rio de Janeiro in Brazil hosted the 'United Nations Conference on Environment and Development' (UNCED). The focus of this conference was the state of the global environment and the relationship between economics, science and the environment in a political context. The conference concluded with the 'Earth Summit', at which leaders of 105 nations gathered to demonstrate their commitment to sustainable development.
Question 10
1 / -0

The species used as natural genetic engineer is

A
Agrobacterium tumefaciens

B
Bacillus thuringiensis

C
Aspergillus

D
Drosophila

Solution

Agrobacterium tumefaciens will transfer genes (T-DNA region of Ti plasmid) into the plant that produces its food or nutrient called opines (opines are not needed for plants). Apart from that, it also integrates genes for cell division and proliferation leading to crown gall disease, so that more number of cells result in more production of opines. Because of this reason it is called as a 'natural genetic engineer'.
