The Eastern Himalayas are a biodiversity hotspot. Which of the following is a major threat to biodiversity in this region?
-
Climate change
-
Deforestation
-
Poaching
-
All of the above
D
Correct answer
Explanation
Climate change, deforestation, and poaching are all major threats to biodiversity in the Eastern Himalayas.
Which of the following human activities is a major threat to the resilience of ecosystems?
-
Sustainable Agriculture
-
Renewable Energy Development
-
Habitat Fragmentation
-
Conservation
C
Correct answer
Explanation
Habitat fragmentation, caused by human activities such as deforestation and urbanization, reduces the connectivity and resilience of ecosystems.
Which of these is a potential long-term consequence of water pollution and environmental racism on ecosystems?
-
Loss of Biodiversity
-
Degradation of Aquatic Habitats
-
Disruption of Food Chains
-
All of the Above
D
Correct answer
Explanation
Water pollution and environmental racism can lead to loss of biodiversity, degradation of aquatic habitats, and disruption of food chains, impacting the overall health of ecosystems.
What are some of the threats to wetlands and mangroves?
-
Pollution
-
Climate change
-
Deforestation
-
All of the above.
D
Correct answer
Explanation
Wetlands and mangroves are threatened by a number of human activities, including pollution, climate change, and deforestation. Pollution can contaminate the water and soil in wetlands, making them uninhabitable for wildlife. Climate change is causing sea levels to rise, which is threatening coastal wetlands. Deforestation is removing trees that help to protect wetlands from erosion and storm damage.

How do carbon emissions contribute to habitat destruction?
-
Direct habitat loss due to deforestation for energy production
-
Increased frequency and intensity of natural disasters
-
Ocean acidification leading to coral reef degradation
-
All of the above
D
Correct answer
Explanation
Carbon emissions contribute to habitat destruction through various mechanisms, including direct habitat loss, increased natural disasters, and ocean acidification.
Which habitat type is particularly vulnerable to the impacts of climate change and carbon emissions?
-
Tropical Rainforests
-
Coral Reefs
-
Arctic Tundra
-
Grasslands
Correct answer
Explanation
Tropical rainforests, coral reefs, Arctic tundra, and grasslands are all highly susceptible to the impacts of climate change and carbon emissions, facing significant threats to their biodiversity and ecological functions.
Which of the following is a major environmental impact of the loss of biodiversity?
-
Reduced ecosystem resilience
-
Increased food production
-
Improved air quality
-
Decreased water pollution
A
Correct answer
Explanation
The loss of biodiversity can reduce the resilience of ecosystems, making them more vulnerable to disturbances and less able to provide essential services.
What is the primary cause of species endangerment and extinction worldwide?
-
Habitat Loss
-
Climate Change
-
Pollution
-
Overpopulation
A
Correct answer
Explanation
Habitat loss, primarily due to deforestation, urbanization, and agricultural expansion, is the leading cause of species endangerment and extinction.
Which of the following is not a major threat to plant conservation?
-
Habitat loss and fragmentation
-
Climate change
-
Overexploitation
-
Pollution
D
Correct answer
Explanation
Pollution is not a major threat to plant conservation compared to habitat loss and fragmentation, climate change, and overexploitation.
How did industrialization contribute to the decline of biodiversity?
-
Increased habitat conservation efforts
-
Adoption of sustainable practices
-
Habitat destruction for resource extraction
-
Enhanced wildlife protection laws
C
Correct answer
Explanation
Industrialization often led to habitat destruction for resource extraction, such as mining and logging, resulting in the decline of biodiversity.
What is the primary cause of coral bleaching, a major threat to coral reefs?
-
Overfishing
-
Pollution
-
Climate Change
-
Habitat Destruction
C
Correct answer
Explanation
Climate change, particularly rising sea temperatures, is the primary cause of coral bleaching, a phenomenon where corals lose their vibrant colors and become susceptible to disease.
