-
All of the above.
D
Correct answer
Explanation
The loss of biodiversity can have a range of negative effects on ecosystem services, including reducing the productivity of ecosystems, making ecosystems more vulnerable to disturbances, and leading to the loss of ecosystem services that are essential for human well-being.
What are some of the challenges to protecting ecosystem diversity?
-
Human population growth and resource consumption.
-
Climate change.
-
Pollution.
-
All of the above.
D
Correct answer
Explanation
The protection of ecosystem diversity faces a number of challenges, including human population growth and resource consumption, climate change, and pollution.
Which of the following is a major threat to biodiversity in India?
-
Habitat loss
-
Pollution
-
Climate change
-
All of the above
D
Correct answer
Explanation
Habitat loss, pollution, and climate change are all major threats to biodiversity in India. Habitat loss is the conversion of natural areas into other uses, such as agriculture, development, or mining. Pollution can contaminate air, water, and soil, and can harm wildlife. Climate change is causing changes in temperature, precipitation, and sea level, which can disrupt ecosystems and harm wildlife.

What are some of the threats to biodiversity in India?
-
Habitat loss
-
Pollution
-
Climate change
-
All of the above
D
Correct answer
Explanation
Biodiversity in India is threatened by a number of factors, including habitat loss, pollution, and climate change. Habitat loss is the conversion of natural areas into other uses, such as agriculture, development, or mining. Pollution can contaminate air, water, and soil, and can harm wildlife. Climate change is causing changes in temperature, precipitation, and sea level, which can disrupt ecosystems and harm wildlife.
What is the term used to describe the loss of biodiversity due to human activities?
-
Habitat Destruction
-
Climate Change
-
Pollution
-
Overexploitation
A
Correct answer
Explanation
Habitat Destruction refers to the loss or degradation of natural habitats due to human activities, such as deforestation, urbanization, and agriculture.
The Amazon rainforest, the largest rainforest in the world, is home to an astonishing variety of plant and animal species. What is the primary threat to its biodiversity?
-
Deforestation
-
Climate change
-
Poaching
-
Invasive species
A
Correct answer
Explanation
Deforestation, primarily for agriculture and logging, is the primary threat to the biodiversity of the Amazon rainforest. The loss of forest habitat leads to the displacement and extinction of numerous species.
The Galapagos Islands, located in the Pacific Ocean, are famous for their unique wildlife, including the iconic giant tortoises. What is the primary reason for their vulnerability to extinction?
-
Habitat loss
-
Climate change
-
Poaching
-
Invasive species
A
Correct answer
Explanation
Habitat loss due to deforestation and agricultural expansion is the primary reason for the vulnerability of giant tortoises in the Galapagos Islands. The destruction of their natural habitat threatens their survival and ability to reproduce.
Which of these is a conservation status assigned to species facing an extremely high risk of extinction in the wild?
-
Critically endangered
-
Endangered
-
Vulnerable
-
Near threatened
A
Correct answer
Explanation
Critically endangered is a conservation status assigned to species facing an extremely high risk of extinction in the wild. These species are at the brink of disappearing from the planet and require immediate conservation efforts to prevent their extinction.
What is the primary cause of overfishing?
-
Increased demand for seafood
-
Bycatch
-
Habitat destruction
-
Climate change
A
Correct answer
Explanation
The primary cause of overfishing is the increased demand for seafood, driven by population growth and rising affluence.
What is the impact of overfishing on marine ecosystems?
-
Disruption of food webs
-
Loss of biodiversity
-
Habitat degradation
-
All of the above
D
Correct answer
Explanation
Overfishing can disrupt food webs, lead to the loss of biodiversity, and degrade marine habitats, all of which have negative consequences for the health and functioning of marine ecosystems.
What is the economic impact of overfishing?
-
Loss of revenue for fishing communities
-
Increased seafood prices
-
Job losses in the fishing industry
-
All of the above
D
Correct answer
Explanation
Overfishing can lead to loss of revenue for fishing communities, increased seafood prices, and job losses in the fishing industry, all of which have negative economic consequences.
Which of the following is NOT a threat to ecosystem diversity?
-
Habitat loss and fragmentation
-
Climate change
-
Pollution
-
Invasive species
Correct answer
Explanation
All of the options listed are threats to ecosystem diversity. Habitat loss and fragmentation reduce the amount of available habitat for species, making them more vulnerable to extinction. Climate change can alter the environmental conditions that species are adapted to, leading to their decline or disappearance. Pollution can contaminate ecosystems and harm species directly or indirectly. Invasive species can compete with native species for resources, leading to the decline or displacement of native species.
What are the potential consequences of ecosystem diversity loss?
-
It can lead to the extinction of species and the loss of genetic diversity.
-
It can disrupt ecosystem services, such as pollination and water purification.
-
It can make ecosystems more vulnerable to the impacts of climate change and other environmental stressors.
-
All of the above.
D
Correct answer
Explanation
Ecosystem diversity loss can have a range of negative consequences, including the extinction of species and the loss of genetic diversity, the disruption of ecosystem services, such as pollination and water purification, and increased vulnerability of ecosystems to the impacts of climate change and other environmental stressors.
Which of the following is NOT a challenge to achieving sustainable development and ecosystem diversity?
-
Climate change
-
Habitat loss and fragmentation
-
Pollution
-
Economic inequality
D
Correct answer
Explanation
While economic inequality is a significant challenge facing many societies, it is not directly related to sustainable development and ecosystem diversity. The other options listed are all major challenges that can hinder the achievement of sustainable development and ecosystem diversity.
