A Correct answer
Explanation

Extinction is the term used to describe the loss of biodiversity.

Multiple choice

Which of the following is NOT a cause of biodiversity loss?

  1. Habitat loss

  2. Pollution

  3. Climate change

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

Natural selection is not a cause of biodiversity loss, as it is a process that drives evolution and increases biodiversity.

Multiple choice

What is the main challenge facing the conservation of Antarctica?

  1. Climate change

  2. Overfishing

  3. Tourism

  4. Pollution
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Climate change is the main challenge facing the conservation of Antarctica. Rising temperatures, melting ice, and changes in weather patterns are threatening the unique ecosystem and biodiversity of the region.

Multiple choice

Which of the following is NOT a potential impact of gabbro quarrying on biodiversity?

  1. Habitat loss

  2. Fragmentation of habitat

  3. Introduction of invasive species

  4. Increased genetic diversity
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Gabbro quarrying is unlikely to increase genetic diversity, as it typically involves the removal of large amounts of rock and soil, which can destroy habitat and fragment populations. Habitat loss and fragmentation can lead to a decrease in genetic diversity, as populations become isolated and less able to exchange genes.

Multiple choice

What is the primary cause of the decline in coral reefs worldwide?

  1. Overfishing

  2. Climate change and ocean acidification

  3. Pollution from coastal development

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

Climate change and ocean acidification, caused by increased carbon dioxide levels, are the primary threats to coral reefs worldwide.

Multiple choice

What is the estimated number of plant and animal species that could go extinct due to deforestation?

  1. 10,000

  2. 50,000

  3. 100,000

  4. 1,000,000
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

It is estimated that up to 100,000 plant and animal species could go extinct due to deforestation, as their habitats are destroyed or fragmented.

Multiple choice

What are some of the challenges facing Important Bird and Biodiversity Areas (IBAs)?

  1. Habitat loss and degradation

  2. Climate change

  3. Pollution

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

IBAs face a variety of challenges, including habitat loss and degradation, climate change, and pollution. These challenges can threaten the survival of the birds and other biodiversity that depend on IBAs.

Multiple choice

  1. Jane Goodall

  2. Dian Fossey

  3. Biruté Galdikas

  4. David Attenborough
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Biruté Galdikas is a Canadian primatologist and anthropologist who has dedicated her life to studying and protecting orangutans in Borneo. She founded the Borneo Orangutan Survival Foundation, which works to conserve orangutans and their habitat, as well as promote sustainable practices in the region.

Multiple choice

What is the main cause of biodiversity loss?

  1. Habitat destruction

  2. Pollution

  3. Climate change

  4. Invasive species
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Habitat destruction is the leading cause of biodiversity loss, as it removes the natural habitats of species and makes it difficult for them to survive.

Multiple choice

Which of the following is NOT a benefit of biodiversity?

  1. Increased resilience to environmental changes

  2. Enhanced ecosystem productivity

  3. Improved human health and well-being

  4. Reduced risk of natural disasters
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Reduced risk of natural disasters is not a direct benefit of biodiversity, as it is not a direct result of the presence of diverse species.

Multiple choice

Which of the following is NOT a threat to biodiversity?

  1. Habitat loss

  2. Pollution

  3. Climate change

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

Sustainable agriculture is not a threat to biodiversity, as it aims to minimize negative impacts on the environment and promote the conservation of natural resources.

Multiple choice
