Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following statements about species richness is correct?

Species richness is highest near the poles.
Species richness is not affected by latitude.
Species richness is highest in the tropics.
Species richness is uniform across ecosystems.
3

According to NCERT, species richness is highest in tropical regions because of their long evolutionary history, relatively stable environment, and greater availability of solar energy.

What is the primary role of national parks in biodiversity conservation?

To allow controlled hunting
To promote agriculture
To provide habitat protection
To allow urban expansion
3

National parks are protected areas used for in situ conservation, where species are conserved in their natural habitats with minimal human interference.

Which of the following is an incorrect statement about genetic diversity?

Genetic diversity allows species to adapt to environmental changes.
Low genetic diversity increases a species' risk of extinction.
Genetic diversity is unnecessary for evolution.
Different populations of a species may have unique genetic variations.
3

Genetic diversity is essential for evolution because it provides the variation upon which natural selection acts.

Which of the following is NOT a biodiversity hotspot associated with India?

Western Ghats–Sri Lanka
Himalaya
Amazon Rainforest
Indo-Burma
3

The biodiversity hotspots associated with India are Himalaya, Indo-Burma, Western Ghats–Sri Lanka, and Sundaland (Nicobar Islands). The Amazon Rainforest is not one of them.

India occupies approximately what percentage of the world's land area?

2.4%
5%
8.1%
12%
1

India occupies about 2.4% of the world's land area but harbours about 8.1% of the world's recorded species.

Which of the following is NOT included in the "Evil Quartet" responsible for biodiversity loss?

Habitat loss and fragmentation
Overexploitation
Pollution
Alien species invasions
3

The NCERT "Evil Quartet" consists of habitat loss and fragmentation, overexploitation, alien species invasions, and co-extinctions. Pollution is not included in this list.

According to NCERT, how many biodiversity hotspots include regions of India?

2
3
4
5
3

India shares four biodiversity hotspots: Himalaya, Indo-Burma, Western Ghats–Sri Lanka, and Sundaland (Nicobar Islands).

Which of the following conservation methods is used to preserve genetic material of endangered species?

Cryopreservation
Wildlife sanctuaries
National parks
Biodiversity hotspots
1

Cryopreservation preserves gametes, embryos, seeds, and other genetic material at very low temperatures as an ex situ conservation method.

Which of the following statements about in situ conservation is incorrect?

It protects species in their natural habitats.
National parks and wildlife sanctuaries are examples of in situ conservation.
It involves removing species from their natural environment.
Biosphere reserves support in situ conservation.
3

In situ conservation protects species in their natural habitats, whereas removing them for conservation is ex situ conservation.

Which of the following is an incorrect statement about biodiversity conservation?

National parks are an example of in situ conservation.
Seed banks store genetic material for conservation.
Zoos provide in situ conservation for endangered species.
Biodiversity conservation helps maintain ecosystem stability.
3

Zoological parks are examples of ex situ conservation because organisms are protected outside their natural habitats.
