Question 1
1 / -0

Arrange in ascending order on the basis of numbers in India.
(1) Biosphere reserves (2) Hotspots (3) National Parks (4) Wildlife sanctuaries

A
2 1 3 4

B
2 3 4 1

C
1 2 3 4

D
4 3 2 1

Solution

A) In India, we have 18 Biosphere reserves.
B) In India, we have 4 Hotspots.
C) In India, we have 166 National parks.
D) In India, we have 515 Wildlife sanctuaries.
So, the correct answer is '2 1 3 4'.
Question 2
1 / -0

India is one of the twelve megadiversity countries with ______ of genetic resources of the world.

A
12.1%

B
18.1%

C
38.1%

D
8.1%

Solution

Although India has only 2.4 per cent of the world’s land area. But its share of the global species diversity is an impressive 8.1 percent. That is what makes our country one of the 12 megadiversity countries of the world. Nearly 45,000 species of plants and twice as many of animals have been recorded from India.
So, the correct answer is '8.1%'.
Question 3
1 / -0

Kokkarebellur bird sanctuary is located in

A
Mandya

B
Mysore

C
Chamarajnagar

D
Hassan

Solution

Kokkarebellur Bird Sanctuary is located in Mandya, Karnataka. A naturally occurring sanctuary, such as an island, which protects species from getting hunted, predated or poached is called as a wildlife refuge. It is also known as a wildlife sanctuary. Being a protected area, it is a geographic territory within which wildlife is protected. 515 wildlife sanctuaries are present in India currently.
So, the correct answer is 'Mandya'.
Question 4
1 / -0

Percentage of angiosperms of all the threatened species is

A
51%

B
42%

C
28%

D
18%

Solution

IUCN is the authority on threatened species, and it treats threatened species as a group of three categories, depending on the degree relative to which they are threatened. Those categories are Vulnerable species; Endangered species and Critically endangered species. As per the Red list of 2000, there are 11,096 threatened species. The percentage of angiosperms of all the threatened species is 51%.
So, the correct answer is '51%'.
Question 5
1 / -0

Which one is not used for ex-situ plant conservation?

A
Botanical gardens

B
Field gene bank

C
Seed banks

D
Shifting cultivation

Solution

Ex-situ conservation is done by preserving the components of biological diversity outside their natural habitats. It is done by conserving genetic resources, as well as wild and cultivated or species. Examples include gene banks, microbial cultures, cryopreservation, seed banks, botanical gardens, etc. Whereas, shifting cultivation is the process of slash and burn agriculture.
So, the correct answer is 'Shifting cultivation'.
Question 6
1 / -0

Find the wrongly matched pair.

A
Endemism- Species confined to one region and not found anywhere else

B
Hotspots- Regions with species richness

C
Alien species to India- Clarias gariepinus

D
Lungs of the planet- Amazon rain forest

E
In situ conservation- IVF

Solution

A) Endemism - Species confined to one region and not found anywhere else is called endemic species.

B) Hotspots - Regions with species richness are called hotspots.

C) Clarias gariepinus- Is an alien species to India.

D) Amazon rain forest - Is known as 'Lungs of the planet'.

E) IVF- Stands for In Vitro Fertilization, not a method of In situ conservation.

So, the correct answer is 'In situ conservation IVF'.
Question 7
1 / -0

Maximum biodiversity is found in

A
Tropical rain forests

B
Temperate rain forests

C
Mangrove vegetation

D
Tundra

Solution

Maximum biodiversity is found in Tropical rain forests. One of the reasons is that tropical environments, unlike temperate ones, are less seasonal, relatively more constant and predictable. Such constant environments promote niche specialization and lead to greater species diversity. Examples:-
A) A forest in a tropical region like Equador has up to 10 times as many species of vascular plants as a forest of equal area in a temperate region like the Midwest of the USA.
B) The largely tropical Amazonian rain forest in South America has the greatest biodiversity on earth- it is home to more than 40,000 species of plants, 3,000 of fishes, 1,300 of birds, 427 of mammals, 427 of amphibians, 378 of reptiles and of more than 1,25,000 invertebrates.
So, the correct answer is 'Tropical rain forests'.
Question 8
1 / -0

One of the chief reasons among the following for the depletion in the number of species making it endangered is

A
Greenhouse effect

B
Habitat destruction

C
Overhunting and poaching

D
Competition and predation

Solution

Jarod Diamond in 1984 listed four chief 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 'Habitat destruction'.
Question 9
1 / -0

Given here is representation of global diversity of invertebrates. What groups of four portions (a- d) represent respectively?

A
a- Crustaceans, b- Insects, c- Molluscs, d- Other animal groups

B
a- Molluscs, b- Other animal groups, c- Crustaceana, d- Insects

C
a- Insects, b- Molluscs, c- Crustaceana, d- Other animal groups

D
a- Insects, b- Crustaceans, c- Other animal groups, d- Molluscs

Solution

A) Among animals, insects are the most species-rich taxonomic group, making up more than 70 percent of the total. That means, out of every 10 animals on this planet, 7 are insects.
B) Other animals occupy the second position.
C) Molluscs are third among the group of invertebrates.
D) Crustaceans are least in number.
So, the correct answer is 'a- Insects, b- Molluscs, c- Crustaceana, d- Other animal groups'.
Question 10
1 / -0

The number of taxa present within a particular area or an ecosystem is

A
$$\alpha$$ - diversity

B
$$\beta$$ - diversity

C
Gamma diversity

D
Delta diversity

Solution

The number of taxa present within a particular area or an ecosystem is called alpha diversity. It is also the diversity present within the community. The term was introduced by R. H. Whittaker. Example of such diversity includes high tree diversity throughout the Amazon Rainforests of Ecuador. Generally, gamma diversity = alpha diversity x beta diversity.
So, the correct answer is 'α - diversity'.
