Correct answer Carries: 4.

Wrong Answer Carries: -1.

Which of the following is an example of in situ conservation?

Zoological parks
Seed banks
Wildlife sanctuaries
Cryopreservation
3

Wildlife sanctuaries are an example of in situ conservation, where species are protected in their natural habitats.

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

National parks
Wildlife sanctuaries
Zoological parks
Biosphere reserves
3

Zoological parks protect organisms outside their natural habitats and are therefore examples of ex situ conservation.

Which of the following is an example of an ecosystem service?

Photosynthesis
Soil formation
Pollination
All of the above
4

Photosynthesis, soil formation, and pollination are ecosystem services provided by biodiversity that support life on Earth.

Which type of diversity is essential for adaptation and survival of a species?

Species diversity
Genetic diversity
Ecosystem diversity
Functional diversity
2

Genetic diversity enables populations to adapt to changing environmental conditions and is essential for evolution.

Which of the following statements about biodiversity hotspots is correct?

Biodiversity hotspots have high species richness and endemism.
Biodiversity hotspots have low conservation value.
Biodiversity hotspots are found only in temperate regions.
All ecosystems on Earth are biodiversity hotspots.
1

Biodiversity hotspots are regions rich in endemic species and are priorities for conservation.

Which of the following is NOT a reason for conserving biodiversity?

Narrowly utilitarian values
Broadly utilitarian values
Ethical values
Monetary inflation
4

NCERT recognizes narrowly utilitarian, broadly utilitarian, and ethical values as reasons for conserving biodiversity. Monetary inflation is unrelated.

Which type of diversity refers to the variety of ecosystems within a given region?

Genetic diversity
Species diversity
Ecosystem diversity
Taxonomic diversity
3

Ecosystem diversity refers to the variety of habitats and ecosystems, such as forests, deserts, wetlands, and coral reefs.

Which of the following is an incorrect statement about the IUCN Red List?

It categorizes species based on extinction risk.
It includes only plant species.
It helps guide conservation efforts.
It lists endangered and critically endangered species.
2

The IUCN Red List includes plants, animals, fungi, and other organisms and classifies them according to their extinction risk.

According to Alexander von Humboldt, species richness increases with increasing explored area, but only up to a limit. This relationship is known as:

Species-area relationship
Competitive exclusion principle
Hardy-Weinberg equilibrium
Ecological succession
1

Alexander von Humboldt described the species-area relationship, where species richness increases with area but only up to a certain limit.

Which category of organisms comprises the largest proportion of described animal species?

Mammals
Fungi
Insects
Birds
3

According to NCERT, insects constitute more than 70% of all described animal species, making them the largest group.
