-
Pollution
-
Climate change
-
Habitat destruction
-
All of the above

What is the term used to describe the loss of species at an alarming rate?
-
Endangered Species
-
Extinction
-
Habitat Destruction
-
Climate Change
B

Which of the following is a major cause of biodiversity loss?
-
Habitat Destruction
-
Pollution
-
Overpopulation
-
Deforestation
A
Correct answer
Explanation
Habitat destruction, often caused by human activities, is a leading cause of biodiversity loss.
What are the implications of coral bleaching for marine ecosystems?
-
It leads to a decline in biodiversity
-
It disrupts the food chain
-
It affects coastal protection
-
All of the above
D
Correct answer
Explanation
Coral bleaching can lead to a decline in biodiversity, disruption of the food chain, and reduced coastal protection. Coral reefs provide habitat for a wide variety of marine life, and their loss can have a ripple effect on the entire ecosystem.
What are some of the threats to natural heritage?
-
Pollution.
-
Deforestation.
-
Climate change.
-
All of the above.
D
Correct answer
Explanation
Natural heritage is threatened by pollution, deforestation, climate change, and other factors.
What is the main threat to coral reefs from overfishing?
-
The removal of herbivorous fish
-
The removal of predatory fish
-
The removal of reef-building fish
-
The removal of all types of fish
A
Correct answer
Explanation
Herbivorous fish eat algae, which helps to keep the coral reef clean and healthy. When herbivorous fish are removed from the reef, the algae can overgrow and smother the coral.
Which of the following is a common threat to wildlife?
-
Habitat loss
-
Pollution
-
Climate change
-
All of the above
D
Correct answer
Explanation
Habitat loss, pollution, and climate change are all major threats to wildlife.

-
Deforestation
-
Habitat loss
-
Climate change
-
Pollution
D
Correct answer
Explanation

What are some of the potential negative impacts of unsustainable tourism in mountain and hill stations?
-
Environmental degradation
-
Loss of biodiversity
-
Cultural erosion
-
All of the above
D
Correct answer
Explanation
Unsustainable tourism practices in mountain and hill stations can lead to environmental degradation, such as deforestation, soil erosion, and water pollution; loss of biodiversity due to habitat destruction and overexploitation of natural resources; and cultural erosion as local traditions and customs are compromised to cater to tourist demands.
Which of the following is NOT a threat to biodiversity?
-
Habitat loss
-
Climate change
-
Pollution
-
Invasive species
D
Correct answer
Explanation
Habitat loss, Climate change, and Pollution are all threats to biodiversity, while Invasive species is not.
Which of the following is NOT a potential environmental impact of migration?
-
Deforestation
-
Pollution
-
Biodiversity loss
-
Economic growth
D
Correct answer
Explanation
Migration can have various environmental impacts, including deforestation, pollution, and biodiversity loss. However, economic growth is not a direct environmental impact of migration.
How does migration contribute to the spread of invasive species?
-
Migrants bring invasive species with them.
-
Migrants create new habitats for invasive species.
-
Migrants increase the demand for resources, which leads to the introduction of invasive species.
-
All of the above
D
Correct answer
Explanation
Migration can contribute to the spread of invasive species through various mechanisms. Migrants may bring invasive species with them, either intentionally or unintentionally. They may also create new habitats for invasive species by clearing forests or converting natural areas to agricultural land. Additionally, migration can increase the demand for resources, such as food and water, which can lead to the introduction of invasive species to meet this demand.
