Multiple choice

What is functional diversity?

  1. The variety of roles and functions that different species play within an ecosystem

  2. The number of different species in an ecosystem

  3. The genetic diversity of a population

  4. The physical characteristics of an ecosystem
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Functional diversity encompasses the range of traits, behaviors, and ecological roles that species exhibit within a community.

Multiple choice

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

  1. Species richness

  2. Species evenness

  3. Functional traits

  4. Functional redundancy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Species richness, while related to functional diversity, is not a direct component of it. Functional diversity focuses on the diversity of functions and roles, rather than simply the number of species.

Multiple choice

What is functional redundancy?

  1. The overlap in functional traits among different species

  2. The degree to which different species perform the same function

  3. The number of species that can perform a particular function

  4. The ability of an ecosystem to recover from disturbances
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Functional redundancy refers to the extent to which multiple species within an ecosystem share similar functional traits and perform similar ecological roles.

Multiple choice

How can functional diversity be measured?

  1. By calculating the number of functional traits in a community

  2. By measuring the overlap in functional traits among different species

  3. By assessing the contribution of different species to ecosystem functioning

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

Functional diversity can be quantified using various methods, including trait-based approaches, functional trait diversity indices, and measures of ecosystem functioning.

Multiple choice

What is functional diversity mining?

  1. The process of identifying and extracting valuable compounds from plants based on their functional traits

  2. The exploration of new ecosystems for potential drug discovery

  3. The use of functional diversity to design and manage ecosystems for specific purposes

  4. The study of the relationship between functional diversity and ecosystem services
Reveal answer Fill a bubble to check yourself
