  2. Climate change

  3. Invasive species

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

While habitat loss, climate change, and pollution are all major threats to biodiversity, invasive species are not considered a threat in this context.

Multiple choice

How do invasive species impact native species?

  1. They compete for resources

  2. They transmit diseases

  3. They alter ecosystem dynamics

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

Invasive species can impact native species through competition for resources, transmission of diseases, and alteration of ecosystem dynamics.

Multiple choice

Which of the following is NOT a benefit of species diversity?

  1. Increased ecosystem stability

  2. Enhanced ecosystem resilience

  3. Increased food security

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

While species diversity is associated with increased ecosystem stability, resilience, and food security, it is not directly linked to a reduced risk of disease outbreaks.

Multiple choice

Which of the following is NOT a potential consequence of invasive species?

  1. Economic losses

  2. Loss of biodiversity

  3. Increased food production

  4. Reduced water quality
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Invasive species are typically associated with negative consequences such as economic losses, loss of biodiversity, and reduced water quality, but they do not directly contribute to increased food production.

Multiple choice

  1. It leads to the loss of habitat for many species

  2. It reduces the genetic diversity of plant and animal populations

  3. It contributes to the extinction of species

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

Multiple choice

How does habitat fragmentation impact biodiversity?

  1. It increases genetic diversity.

  2. It reduces the number of species in an ecosystem.

  3. It promotes the spread of invasive species.

  4. It enhances the resilience of ecosystems.
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Habitat fragmentation reduces biodiversity by isolating populations, limiting their ability to interact and reproduce, and making them more vulnerable to extinction.

Multiple choice

Which of the following is a consequence of habitat fragmentation for wildlife populations?

  1. Increased genetic diversity

  2. Reduced dispersal and migration

  3. Enhanced predator-prey interactions

  4. Improved access to food resources
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Habitat fragmentation reduces the ability of wildlife to disperse and migrate, as they face barriers such as roads, fences, and cleared land, which can lead to population isolation and genetic bottlenecks.
