What is the primary cause of the current extinction crisis?
-
Habitat loss and fragmentation
-
Climate change
-
Pollution
-
Overexploitation of resources
A
Correct answer
Explanation

-
Habitat loss and fragmentation
-
Climate change
-
Invasive species
-
Sustainable use of resources
D
Correct answer
Explanation
Sustainable use of resources is not a threat to biodiversity, but rather a way to use resources in a way that does not deplete them or harm the environment.

-
Endangerment
-
Extinction
-
Vulnerability
C
Correct answer
Explanation
Extinction is the term for the process by which a species becomes extinct, meaning that there are no more living members of that species left on Earth.
Which of the following is a key factor to consider when managing wildlife diseases?
-
Habitat fragmentation
-
Climate change
-
Vaccination programs

Which of the following is NOT a major threat to Indian biodiversity?
-
Habitat loss
-
Pollution
-
Overexploitation
-
Deforestation
D
Correct answer
Explanation
Deforestation is a major threat to biodiversity in many parts of the world, but it is not a major threat to Indian biodiversity. India has a relatively low rate of deforestation compared to other countries.

-
Poaching and illegal wildlife trade
-
Habitat loss and fragmentation
-
Human-wildlife conflict
-
Climate change
Correct answer
Explanation
National Parks and Wildlife Sanctuaries in India face a number of challenges, including poaching and illegal wildlife trade, habitat loss and fragmentation, human-wildlife conflict, and climate change.
What are some of the threats to cultural landscapes?
-
Climate change
-
Pollution
-
Urbanization
-
All of the above
D
Correct answer
Explanation
Cultural landscapes are threatened by a number of factors, including climate change, pollution, and urbanization. Climate change can cause changes to the environment that can damage or destroy cultural landscapes. Pollution can also damage cultural landscapes, by causing air and water pollution that can harm plants and animals. Urbanization can lead to the destruction of cultural landscapes, as land is cleared for development.
