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

Which of the following is NOT an example of an ecosystem service?

  1. Pollination of crops

  2. Purification of water

  3. Climate regulation

  4. Production of food
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Production of food is not an ecosystem service, as it is a direct result of human activity.

Multiple choice

Which of the following is an example of a provisioning ecosystem service?

  1. Pollination of crops

  2. Purification of water

  3. Climate regulation

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

Pollination of crops is an example of a provisioning ecosystem service, as it provides a direct benefit to humans in the form of food.

Multiple choice

Which of the following is an example of a regulating ecosystem service?

  1. Pollination of crops

  2. Purification of water

  3. Climate regulation

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

Climate regulation is an example of a regulating ecosystem service, as it helps to maintain the stability of the Earth's climate.

Multiple choice

What is the Millennium Ecosystem Assessment?

  1. A global assessment of the state of ecosystem services

  2. A global assessment of the impact of climate change on ecosystems

  3. A global assessment of the impact of pollution on ecosystems

  4. A global assessment of the impact of habitat loss on ecosystems
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Millennium Ecosystem Assessment is a global assessment of the state of ecosystem services.
