  1. Climate change

  2. Habitat loss

  3. Pollution

  4. Overpopulation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Habitat loss is the leading cause of extinction, as it destroys the homes and resources that species need to survive.

Multiple choice

Which group of organisms is most vulnerable to extinction?

  1. Mammals

  2. Birds

  3. Reptiles

  4. Amphibians
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Amphibians are the most vulnerable group of organisms to extinction, due to their sensitivity to changes in their environment.

Multiple choice

What is the term for the idea that the current mass extinction event is a combination of natural and human-caused factors?

  1. The Anthropocene

  2. The Sixth Extinction

  3. The Great Dying

  4. The Combined Extinction Hypothesis
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Combined Extinction Hypothesis is the idea that the current mass extinction event is a combination of natural and human-caused factors.

Multiple choice

Which of the following is NOT a challenge faced by ecotourism?

  1. Overcrowding.

  2. Pollution.

  3. Habitat destruction.

  4. Economic benefits.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Economic benefits are not a challenge faced by ecotourism, but rather an opportunity.

Multiple choice

How does basalt quarrying impact the visual landscape?

  1. Creation of scenic vistas

  2. Enhancement of natural beauty

  3. Disruption of natural ecosystems

  4. Degradation of aesthetic value
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Basalt quarrying can result in the degradation of the aesthetic value of the surrounding landscape due to the removal of vegetation and the creation of large pits and scars.

Multiple choice

Which of the following is a potential ecological impact of basalt quarrying?

  1. Habitat loss for wildlife

  2. Disruption of food chains

  3. Alteration of hydrological cycles

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Basalt quarrying can have a range of ecological impacts, including habitat loss for wildlife, disruption of food chains, and alteration of hydrological cycles.

Multiple choice

How does forest fragmentation affect the resilience of forest ecosystems?

  1. It increases the risk of fire and insect outbreaks

  2. It reduces biodiversity

  3. It disrupts ecosystem processes

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Forest fragmentation increases the risk of fire and insect outbreaks, reduces biodiversity, and disrupts ecosystem processes, all of which can reduce the resilience of forest ecosystems.

Multiple choice

  1. Polar bears

  2. Coral reefs

  3. Tropical rainforests

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Polar bears, coral reefs, and tropical rainforests are all highly vulnerable to climate change.

Multiple choice

Which of the following is an example of a habitat loss and fragmentation?

  1. Deforestation

  2. Urbanization

  3. Agriculture

  4. All of the above.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Deforestation, urbanization, and agriculture are all examples of habitat loss and fragmentation.

Multiple choice

How does deforestation contribute to the loss of biodiversity?

  1. It increases habitat fragmentation.

  2. It enhances species diversity.

  3. It promotes genetic variation.

  4. It improves ecosystem resilience.
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Deforestation leads to habitat fragmentation, which isolates populations of species and reduces their genetic diversity, increasing the risk of extinction.
