Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The Convention on Biological Diversity (CBD) was signed on June 5, 1992, in Rio de Janeiro, Brazil. It aims to conserve biological diversity, promote sustainable use of biological resources, and ensure the fair and equitable sharing of benefits from the use of genetic resources.

Multiple choice

Why is functional diversity important for fisheries?

  1. It helps to maintain the stability of fish populations

  2. It increases the resilience of fish communities to disturbances

  3. It enhances the productivity of fisheries

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

Functional diversity is important for fisheries because it helps to maintain the stability of fish populations, increases the resilience of fish communities to disturbances, and enhances the productivity of fisheries. By having a variety of functional traits, fish communities are better able to adapt to changes in their environment and to withstand the impacts of fishing.

Multiple choice

How can functional diversity be used to manage fisheries?

  1. By identifying and protecting key functional groups

  2. By developing fishing regulations that target specific functional traits

  3. By restoring degraded habitats that support a variety of functional traits

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

Functional diversity can be used to manage fisheries by identifying and protecting key functional groups, developing fishing regulations that target specific functional traits, and restoring degraded habitats that support a variety of functional traits.

Multiple choice

What is the importance of understanding carrying capacity and limiting factors in conservation biology?

  1. It helps us to predict how populations will respond to environmental changes.

  2. It helps us to manage populations to prevent them from exceeding their carrying capacity.

  3. It helps us to identify and mitigate threats to endangered species.

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

Understanding carrying capacity and limiting factors is important in conservation biology because it helps us to predict how populations will respond to environmental changes, manage populations to prevent them from exceeding their carrying capacity, and identify and mitigate threats to endangered species.

Multiple choice
