Biodiversity and Conservation Questions
Which provisioning service is particularly important for indigenous communities?
-
Timber for construction
-
Water for irrigation
-
Non-timber forest products
-
Minerals for mining
C
Correct answer
Explanation
Non-timber forest products (NTFPs) are an important provisioning service for indigenous communities as they provide a variety of resources for food, medicine, shelter, and other cultural practices. These products include fruits, nuts, seeds, mushrooms, and medicinal plants.
What are the potential environmental impacts of tourism?
-
Increased pollution and waste generation
-
Overcrowding and degradation of natural resources
-
Deforestation and habitat loss
-
All of the above
D
Correct answer
Explanation
Tourism can have negative environmental impacts, including increased pollution and waste generation, overcrowding and degradation of natural resources, and deforestation and habitat loss.
Which of the following is NOT a potential benefit of MPAs?
-
Protection of marine biodiversity and habitats
-
Enhancement of fish stocks and fisheries productivity
-
Mitigation of climate change impacts on marine ecosystems
-
Increased coastal erosion and shoreline degradation
D
Correct answer
Explanation
MPAs are designed to protect and conserve marine ecosystems, not to cause coastal erosion or shoreline degradation. In fact, they can contribute to coastal resilience by protecting habitats that buffer shorelines from erosion.
Which of the following is NOT a potential consequence of overfishing in marine ecosystems?
-
Depletion of fish stocks and reduced漁獲量
-
Disruption of marine food webs and ecological imbalances
-
Increased biodiversity and resilience of marine ecosystems
-
Habitat degradation and loss of critical marine habitats
C
Correct answer
Explanation
Overfishing typically leads to declines in fish stocks, disruption of food webs, habitat degradation, and reduced biodiversity. It does not contribute to increased biodiversity or resilience in marine ecosystems.
What are some of the environmental impacts of adventure tourism?
-
Erosion
-
Pollution
-
Habitat destruction
-
All of the above
D
Correct answer
Explanation
Adventure tourism can have a number of negative environmental impacts, including erosion, pollution, and habitat destruction.
Which of the following is NOT a factor that can affect the value of an ecosystem service?
-
Supply and demand
-
Scarcity
-
Government regulations
-
Cultural preferences
C
Correct answer
Explanation
Government regulations do not directly affect the value of an ecosystem service, but they can affect the way that the service is used or managed.
Which of the following is NOT a benefit of ecosystem diversity?
-
Increased resilience to environmental change
-
Enhanced productivity
-
Reduced risk of disease outbreaks
-
Increased economic stability
D
Correct answer
Explanation
Ecosystem diversity does not directly affect economic stability, although it can have indirect effects on the economy.
What is the term used to describe the loss of ecosystem services due to human activities?
-
Ecosystem degradation
-
Ecosystem collapse
-
Biodiversity loss
-
Habitat fragmentation
A
Correct answer
Explanation
Ecosystem degradation is the process by which the quality or quantity of ecosystem services is reduced.
Which of the following is NOT a consequence of ecosystem degradation?
-
Reduced food production
-
Increased water pollution
-
Loss of biodiversity
-
Improved air quality
D
Correct answer
Explanation
Ecosystem degradation can lead to a decrease in air quality, but it can also lead to an increase in air quality in some cases.
What are some of the potential consequences of ocean acidification for marine ecosystems?
-
Loss of biodiversity
-
Disruption of food chains
-
Reduced productivity of fisheries
-
All of the above
D
Correct answer
Explanation
Ocean acidification can lead to loss of biodiversity, disruption of food chains, and reduced productivity of fisheries, all of which can have significant impacts on marine ecosystems.
What is the main cause of biodiversity loss in India?
-
Habitat Destruction
-
Pollution
-
Climate Change
-
Overpopulation
A
Correct answer
Explanation
Habitat destruction is the main cause of biodiversity loss in India.
What are some of the challenges to conserving biodiversity in India?
-
Habitat Destruction
-
Pollution
-
Climate Change
-
All of the above
D
Correct answer
Explanation
Habitat destruction, pollution, climate change, and other factors pose challenges to conserving biodiversity in India.
Which of the following is NOT a consequence of overfishing?
-
Depletion of fish stocks
-
Loss of biodiversity
-
Increased food security
-
Damage to marine ecosystems
C
Correct answer
Explanation
Overfishing leads to depletion of fish stocks, loss of biodiversity, and damage to marine ecosystems, but it does not increase food security.
How does biodiversity loss affect primary production?
-
It has no effect
-
It increases primary production
-
It decreases primary production
-
It can have both positive and negative effects
D
Correct answer
Explanation
Biodiversity loss can have both positive and negative effects on primary production, depending on the specific ecosystem and the species involved.
Which of the following is NOT a consequence of climate change on biodiversity?
-
Increased species extinction rates
-
Shifts in species' ranges
-
Changes in species' behavior
-
Increased species' resilience
D
Correct answer
Explanation
Climate change is causing species to become more vulnerable to extinction, not more resilient.
