Which of the following is not a component of functional diversity?

  1. Species richness

  2. Functional evenness

  3. Functional divergence

  4. Functional redundancy


Correct Option: A
Explanation:

Species richness is a measure of the number of species in a community, while functional diversity is a measure of the variety of functions performed by those species.

Which of the following is not a measure of functional diversity?

  1. Functional richness

  2. Functional evenness

  3. Functional divergence

  4. Shannon diversity index


Correct Option: D
Explanation:

The Shannon diversity index is a measure of species diversity, while functional diversity is a measure of the variety of functions performed by those species.

Which of the following is not a benefit of functional diversity?

  1. Increased ecosystem stability

  2. Increased ecosystem productivity

  3. Increased ecosystem resistance to invasion

  4. Increased ecosystem resilience to disturbance


Correct Option: C
Explanation:

Functional diversity is not directly related to ecosystem resistance to invasion, but it can contribute to ecosystem stability, productivity, and resilience to disturbance.

Which of the following is not a factor that can influence functional diversity?

  1. Environmental conditions

  2. Species interactions

  3. Evolutionary history

  4. Climate change


Correct Option: D
Explanation:

Climate change is not a direct factor that influences functional diversity, but it can indirectly affect functional diversity by altering environmental conditions and species interactions.

Which of the following is not a consequence of functional diversity loss?

  1. Decreased ecosystem stability

  2. Decreased ecosystem productivity

  3. Increased ecosystem resistance to invasion

  4. Decreased ecosystem resilience to disturbance


Correct Option: C
Explanation:

Functional diversity loss can lead to decreased ecosystem stability, productivity, and resilience to disturbance, but it does not directly affect ecosystem resistance to invasion.

Which of the following is not a method for measuring functional diversity?

  1. Trait-based approaches

  2. Phylogenetic approaches

  3. Community-weighted mean traits

  4. Species richness


Correct Option: D
Explanation:

Species richness is a measure of species diversity, while functional diversity is a measure of the variety of functions performed by those species.

Which of the following is not a type of functional trait?

  1. Morphological traits

  2. Physiological traits

  3. Behavioral traits

  4. Species richness


Correct Option: D
Explanation:

Species richness is a measure of species diversity, while functional traits are characteristics of individual organisms that influence their ecological roles.

Which of the following is not a way to promote functional diversity?

  1. Conserving and restoring habitats

  2. Reducing pollution

  3. Promoting sustainable land management practices

  4. Introducing non-native species


Correct Option: D
Explanation:

Introducing non-native species can disrupt ecosystem functioning and reduce functional diversity.

Which of the following is not a benefit of functional redundancy?

  1. Increased ecosystem stability

  2. Increased ecosystem productivity

  3. Increased ecosystem resistance to invasion

  4. Increased ecosystem resilience to disturbance


Correct Option: C
Explanation:

Functional redundancy is not directly related to ecosystem resistance to invasion, but it can contribute to ecosystem stability, productivity, and resilience to disturbance.

Which of the following is not a consequence of functional diversity loss?

  1. Decreased ecosystem stability

  2. Decreased ecosystem productivity
