Question 1
1 / -0

The most biodiversity rich zone in India is

A
Gangetic planes

B
Trans himalayas

C
Western ghats

D
Central India
Solution
- Biodiversity hot spots are areas with high density of biodiversity or megadiversity.
- The Western Ghats occur along the western coast of India for a distance of about 1600 km in Maharashtra, Karnataka, Tamil Nadu and Kerala extending over to Sri Lanka.
- At low elevation up to 500 meters above sea level, the area contains tropical evergreen rain forests while semi-evergreen forests occur at a height of 500-1000 meters.
- There is a high degree of endemism as well as the richness of species of flowering plants, amphibians, reptiles, some mammals and butterflies. It is the most biodiversity rich zone in India.
Hence, the correct option is C.
Question 2
1 / -0

The state of Gujarat has river, desert, forest and lake ecosystems, thus exhibiting a diversity of life. This is an example of ................. diversity.

A
$$\alpha $$ (alpha)

B
$$\beta $$ (beta)

C
$$\gamma $$ (gamma)

D
$$ \delta $$ (delta)

Solution

Alpha diversity is the species diversity in a given community or habitat. It depends on upon species richness and evenness or equitability.
Beta diversity is biodiversity, which appears in a range of communities due to the replacement of species with the change in community or habitat due to the presence of different microhabitats, niches and differences in environmental conditions.
Gamma diversity is the diversity present in ranges of communities as represented by the diversity of habitats or ecosystems over a total landscape or geographical area.
Delta diversity is defined as the change in species abundance and composition between areas of gamma diversity which occurs within the area of epsilon diversity.
Thus, the correct answer is option C.
Question 3
1 / -0

The presence of diversity at the junction of territories of two different habitats is known as

A
Bottle neck effect

B
Edge effect

C
Warburg effect

D
Pasteur effect

Solution

Ecotone is the transition zone between 2 communities, habitats e.g., forest and grassland. The increased number of species in the region of ecotone is called as edge effect and the species is called as edge species.
Bottleneck effect is described as a phenomenon when the population of a species is reduced to a drastic level and genetic diversity also becomes limited. It generally takes place after overhunting or earthquakes etc.
Warburg effect is the formation of lactic acid from glucose via glycolysis in the cancerous cell even when an adequate amount of oxygen is available.
Pasteur effect is the inhibition of the process of fermentation by supplying oxygen.
Thus, the correct answer is option B.
Question 4
1 / -0

One of the most important functions of botanical gardens is that

A
They provide a beautiful area for recreation.

B
One can observe tropical plants there.

C
They allow ex-situ conservation of germplasm.

D
They provide the natural habitat for wild life.
Solution
Ex-situ conservation is the conservation of selected rare plants/ animals in places outside their natural homes. Ex-situ conservation includes offsite collections and gene banks.
The two are also a source of genetic material for breeders and genetic engineers. Offsite collections are live collections of wild and domesticated species in botanical gardens, zoos, arboreta, etc.
Gene banks are institutes that maintain stocks of viable seeds (seed banks), live growing plants (orchards), tissue culture, and frozen germplasm with the whole range of genetic variability.
So, the correct answer is option C.
Question 5
1 / -0

Biodiversity act of India was passed by the parliament in the year

A
1992

B
1996

C
2000

D
2002
Solution
The Biodiversity Act was passed in 2002 for the protection of India's rich biodiversity and associated knowledge against their exploitation, illegal use by foreign individuals and organizations or without sharing the benefits arising out of such use and to check biopiracy.
So, the correct answer is '2002'
Question 6
1 / -0

Preserving germplasm in frozen state is

A
Cryopreservation

B
Cold storage

C
In situ preservation

D
Vernalization

Solution

Cryopreservation is the preservation of germplasm in the frozen state that is in liquid nitrogen (-196$$^{0}$$C). Cryopreserved materials remain genetically stable.
Question 7
1 / -0

World wild life week is

A
First week of September

B
First week of October

C
Third week of October

D
Last week of October

Solution

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.
Question 8
1 / -0

India became a party to convention on biological diversity in the year

A
1994

B
1993

C
1992

D
1988

Solution

The Earth's Summit was held at Rio de Janeiro in Brazil in 1992. Earth summit at Rio, Brazil, promoted 'Convention on Biological Diversity' (CBD), which was signed by 152 nations. Its recommendations came into effect on 29$$^{th}$$ Dec, 1993. India became a party to this 'Convention on Biological Diversity' in May 1994.
Question 9
1 / -0

In India, we find mangoes with different flavours, colours, fibre content, sugar content and even shelf life. The large variation is in account of

A
Species diversity

B
Induced mutations

C
Genetic diversity

D
Hybridization

Solution

Common mango (Mangifera indica) originated as alloploid and its native home was suggested as Eastern India, Assam to Burma or possibly further in the Malay region (Popenoe, 1920). Vavilov (1926) also suggested Indo-Burma region as the centre of origin of mango. Hence, mango shows maximum genetic diversity in India.
Question 10
1 / -0

Which one of the following has maximum genetic diversity in India?

A
Teak

B
Mango

C
Wheat

D
Tea

Solution

India is one of the twelve megadiversity regions of the world with 7.7 percent of genetic resources of the world.
Western Ghats have wild relatives of a number of cultivated plants like banana, citrus, mango, pepper etc.
Common mango (Mangifera indica) originated as alloploid and its native home was suggested as Eastern India, Assam to Burma or possibly further in the Malay region (Popenoe, 1920).
Vavilov (1926) also suggested Indo-Burma region as the centre of origin of mango. Hence, mango shows maximum genetic diversity in India.
