C Correct answer
Explanation

Increased biodiversity is not a potential benefit of marine and coastal zone management in addressing invasive species, as invasive species can reduce biodiversity by outcompeting native species and altering ecosystem structure and function.

Multiple choice

Which of the following is not a common indicator used to assess the effectiveness of marine and coastal zone management in addressing invasive species?

  1. Invasive species abundance

  2. Native species abundance

  3. Habitat condition

  4. Economic losses

D Correct answer
Explanation

Economic losses are not a common indicator used to assess the effectiveness of marine and coastal zone management in addressing invasive species, as they can be difficult to quantify and may not always be directly attributable to invasive species.

Multiple choice

Which of the following is not a potential consequence of invasive species in marine and coastal ecosystems?

  1. Reduced biodiversity

  2. Altered ecosystem structure and function

  3. Increased ecosystem resilience

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

Increased ecosystem resilience is not a potential consequence of invasive species in marine and coastal ecosystems, as invasive species can reduce ecosystem resilience by disrupting ecological interactions and altering ecosystem structure and function.
