-
Deforestation for agriculture
-
Mining and quarrying
-
Urbanization and infrastructure development
-
All of the above
D
Correct answer
Explanation
Habitat loss and fragmentation in wildlife sanctuaries and national parks in India are primarily caused by deforestation for agriculture, mining and quarrying, and urbanization and infrastructure development.
What is the main reason for the decline in elephant populations in India?
-
Habitat loss and fragmentation
-
Poaching for ivory
-
Human-elephant conflict
-
All of the above
D
Correct answer
Explanation
The decline in elephant populations in India is primarily due to habitat loss and fragmentation, poaching for ivory, and human-elephant conflict.
What is the primary cause of human-wildlife conflict in India?
-
Habitat loss and fragmentation
-
Competition for resources
-
Expansion of human settlements
-
All of the above
D
Correct answer
Explanation
Human-wildlife conflict in India is primarily caused by habitat loss and fragmentation, competition for resources, and the expansion of human settlements.
How does industrialization contribute to the loss of biodiversity?
-
By introducing invasive species
-
By creating new habitats for wildlife
-
By reducing pollution levels
-
By increasing the availability of food resources
A
Correct answer
Explanation
Industrial activities can lead to the introduction of non-native species into new environments, which can outcompete native species and disrupt ecosystems.
Which of the following is an example of a challenge to promoting ecosystem services?
-
Climate change
-
Pollution
-
Habitat loss
-
All of the above
D
Correct answer
Explanation
Climate change, pollution, and habitat loss are all examples of challenges to promoting ecosystem services because they can damage or destroy ecosystems, resulting in the loss of ecosystem services.
Which of the following is NOT a major threat to coral reefs?
-
Climate change
-
Overfishing
-
Pollution
-
Coral bleaching
D
Correct answer
Explanation
Coral bleaching is a symptom of stress experienced by corals, often caused by elevated water temperatures or pollution. It is not a direct threat to coral reefs, but rather a consequence of other stressors.
Which of the following is NOT a major threat to the survival of coral reefs?
-
Climate change
-
Overfishing
-
Pollution
-
Natural disasters
D
Correct answer
Explanation
Natural disasters, such as hurricanes and tsunamis, can cause damage to coral reefs, but they are not considered a major threat to their survival compared to human-induced stressors like climate change and pollution.
What is the main focus of environmental activism in the Antarctic region?
-
Climate change impacts
-
Overfishing
-
Pollution
-
Habitat destruction
A
Correct answer
Explanation
Environmental activists in the Antarctic region are primarily concerned with the effects of climate change, such as melting ice sheets, rising sea levels, and disruptions to ecosystems.
Which of the following is a major threat to river and lake biodiversity?
-
Climate change
-
Pollution
-
Habitat destruction
-
Overfishing
B
Correct answer
Explanation
Pollution from industrial waste, agricultural runoff, and sewage discharge poses a significant threat to the health of river and lake ecosystems.
Which of the following is a key challenge to biodiversity conservation in India?
-
Habitat loss
-
Pollution
-
Climate change
-
All of the above
D
Correct answer
Explanation
Habitat loss, pollution, and climate change are all key challenges to biodiversity conservation in India. Habitat loss is caused by deforestation, urbanization, and other forms of land use change. Pollution can contaminate water, air, and soil, and can harm wildlife. Climate change is causing the Earth's temperature to rise, which can lead to changes in precipitation patterns, sea level rise, and other disruptions to ecosystems.
Which of the following beverages is the most likely to be associated with biodiversity loss?
A
Correct answer
Explanation
Juice production is often associated with biodiversity loss, as the cultivation of fruit trees can contribute to deforestation and the loss of habitat for wildlife. Milk, soda, and water production can also be associated with biodiversity loss, but to a lesser extent than juice.
Which of the following beverages is the most likely to be associated with biodiversity loss?
A
Correct answer
Explanation
Juice production is often associated with biodiversity loss, as the cultivation of fruit trees can contribute to deforestation and the loss of habitat for wildlife. Milk, soda, and water production can also be associated with biodiversity loss, but to a lesser extent than juice.
What is the main reason for the decline of near threatened species in India?
-
Habitat loss
-
Pollution
-
Climate change
-
All of the above
D
Correct answer
Explanation
Near threatened species in India are declining due to a combination of factors, including habitat loss, pollution, and climate change.
What are the economic consequences of desertification?
-
Loss of agricultural productivity
-
Loss of biodiversity
-
Loss of tourism revenue
-
All of the above
D
Correct answer
Explanation
