Multiple choice

What is functional diversity?

  1. The variety of functional traits within a community or ecosystem

  2. The number of different species within a community or ecosystem

  3. The genetic diversity within a population

  4. The diversity of habitats within a landscape
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Functional diversity refers to the variety of functional traits, or the different ways in which organisms perform their ecological roles, within a community or ecosystem.

Multiple choice

How is functional diversity related to ecosystem functioning?

  1. Functional diversity has no relationship to ecosystem functioning

  2. Functional diversity has a negative relationship to ecosystem functioning

  3. Functional diversity has a positive relationship to ecosystem functioning

  4. The relationship between functional diversity and ecosystem functioning is unclear
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Functional diversity is positively related to ecosystem functioning because it allows ecosystems to perform a wider range of functions and respond more effectively to environmental changes.

Multiple choice

What is the relationship between functional diversity and ecosystem resilience?

  1. Functional diversity has no relationship to ecosystem resilience

  2. Functional diversity has a negative relationship to ecosystem resilience

  3. Functional diversity has a positive relationship to ecosystem resilience

  4. The relationship between functional diversity and ecosystem resilience is unclear
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Functional diversity is positively related to ecosystem resilience because it allows ecosystems to respond more effectively to environmental changes and recover more quickly from disturbances.

Multiple choice

What is the relationship between functional diversity and biodiversity?

  1. Functional diversity is a subset of biodiversity

  2. Biodiversity is a subset of functional diversity

  3. Functional diversity and biodiversity are unrelated

  4. Functional diversity and biodiversity are synonymous
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Functional diversity is a subset of biodiversity because it refers to the variety of functional traits within a community or ecosystem, while biodiversity refers to the variety of life forms, including species, genes, and ecosystems.

Multiple choice

  1. By measuring the variety of functional traits within a community or ecosystem

  2. By measuring the number of different species within a community or ecosystem

  3. By measuring the genetic diversity within a population

  4. By measuring the diversity of habitats within a landscape
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Functional diversity in the context of renewable energy systems can be measured by measuring the variety of functional traits within a community or ecosystem.
