Biodiversity and Conservation Questions
Which of the following is NOT a key ecosystem service?
-
Pollination
-
Carbon sequestration
-
Biodiversity
-
Air pollution
D
Correct answer
Explanation
Air pollution is not an ecosystem service. It is a negative consequence of human activities that can harm ecosystems and human health.
Which of the following is a major threat to river ecosystems?
-
Pollution
-
Habitat destruction
-
Climate change
-
All of the above
D
Correct answer
Explanation
Pollution, habitat destruction, and climate change are all major threats to river ecosystems, as they can disrupt the delicate balance of these ecosystems and lead to the loss of biodiversity.
Which of the following is a major challenge faced by wildlife conservation in India?
-
Habitat Loss
-
Poaching
-
Climate Change
-
Invasive Species
A
Correct answer
Explanation
Habitat loss due to deforestation, urbanization, and agricultural expansion is a major challenge faced by wildlife conservation in India, as it reduces the available habitat for wildlife and leads to fragmentation of populations.
Which of the following is a major threat to marine wildlife in India?
-
Overfishing
-
Pollution
-
Climate Change
-
Habitat Loss
A
Correct answer
Explanation
Overfishing is a major threat to marine wildlife in India. It leads to the depletion of fish stocks and can disrupt marine ecosystems.
Which of the following is a challenge faced by wildlife conservation in urban areas?
-
Habitat Fragmentation
-
Pollution
-
Human-Wildlife Conflict
-
Invasive Species
C
Correct answer
Explanation
Human-wildlife conflict is a challenge faced by wildlife conservation in urban areas. As urban areas expand, they encroach upon wildlife habitats, leading to increased interactions between humans and wildlife. This can result in conflicts, such as crop raiding by wild animals or attacks on humans by wild animals.
Which of the following is NOT a potential consequence of cyclones and storms on coastal ecosystems?
-
Loss of biodiversity
-
Changes in species composition
-
Increased productivity
-
Alteration of nutrient cycling
C
Correct answer
Explanation
Increased productivity is not a potential consequence of cyclones and storms on coastal ecosystems.
What is the concept of 'spillover effect' in the context of MPAs?
-
The movement of marine species from MPAs to adjacent areas.
-
The migration of marine species from MPAs to distant locations.
-
The increase in species diversity within MPAs over time.
-
The decrease in fishing pressure within MPAs due to regulations.
A
Correct answer
Explanation
The 'spillover effect' refers to the movement of marine species from MPAs to adjacent areas, often due to increased population densities and reduced fishing pressure within MPAs. This can benefit fisheries outside MPAs by replenishing fish stocks and increasing catches.
What are some of the challenges faced by wildlife sanctuaries and national parks in their efforts to conserve biodiversity?
-
Habitat loss and fragmentation.
-
Poaching and illegal wildlife trade.
-
Climate change.
-
Invasive species.
Correct answer
Explanation
Wildlife sanctuaries and national parks face a number of challenges in their efforts to conserve biodiversity, including habitat loss and fragmentation, poaching and illegal wildlife trade, climate change, and invasive species.
What are some of the challenges that wildlife sanctuaries and national parks face in achieving their conservation goals?
-
Habitat loss and fragmentation.
-
Climate change.
-
Invasive species.
-
Poaching and illegal wildlife trade.
Correct answer
Explanation
Wildlife sanctuaries and national parks face a number of challenges in achieving their conservation goals, including habitat loss and fragmentation, climate change, invasive species, and poaching and illegal wildlife trade.
What is the primary environmental concern regarding the cloning of animals?
-
The increased demand for resources
-
The potential for cloned animals to escape and interbreed with wild populations
-
The potential for cloned animals to carry diseases
-
The potential for cloned animals to disrupt ecosystems
D
Correct answer
Explanation
The primary environmental concern regarding the cloning of animals is the potential for cloned animals to disrupt ecosystems by introducing new genetic material and competing with native species for resources.
What is the primary ethical concern regarding the cloning of extinct species?
-
The potential for ecological disruption
-
The commodification of extinct species
-
The potential for genetic contamination
-
The diversion of resources from conservation efforts
A
Correct answer
Explanation
The primary ethical concern regarding the cloning of extinct species is the potential for ecological disruption, as the introduction of cloned animals into ecosystems could have unintended consequences.
Which of the following is NOT a major impact of fertilizers on biodiversity?
-
Eutrophication
-
Acidification
-
Greenhouse Gas Emissions
-
Habitat Loss
D
Correct answer
Explanation
Habitat Loss is not a major impact of fertilizers on biodiversity.
Which natural ecosystem plays a crucial role in mitigating the effects of climate change?
-
Forests
-
Oceans
-
Wetlands
-
All of the above
D
Correct answer
Explanation
Forests, oceans, and wetlands act as carbon sinks, absorbing and storing carbon dioxide from the atmosphere, thereby helping to regulate the global climate.
Which of the following is a major impact of climate change on biodiversity in India?
-
Loss of habitat
-
Changes in species distribution
-
Increased risk of extinction
-
All of the above
D
Correct answer
Explanation
Climate change is leading to loss of habitat, changes in species distribution, and increased risk of extinction, all of which have negative impacts on biodiversity in India.
Which of the following is NOT a factor that can affect the value of ecosystem services?
-
Scarcity
-
Demand
-
Supply
-
Cultural preferences
D
Correct answer
Explanation
Cultural preferences do not directly affect the value of ecosystem services, as they are not related to the economic or ecological value of the services.
