What is functional diversity?

  1. The variety of traits and functions performed by organisms in an ecosystem.

  2. The number of different species in an ecosystem.

  3. The genetic diversity within a population.

  4. The physical structure of an ecosystem.


Correct Option: A
Explanation:

Functional diversity refers to the variety of roles and functions that different species play in an ecosystem, such as pollination, seed dispersal, and nutrient cycling.

How does urbanization affect functional diversity?

  1. It increases functional diversity by creating new habitats for species.

  2. It decreases functional diversity by reducing the number of species in an area.

  3. It has no effect on functional diversity.

  4. It increases functional diversity by increasing the number of species in an area.


Correct Option: B
Explanation:

Urbanization typically leads to a decrease in functional diversity because it reduces the number of species in an area, as well as the variety of habitats available to them.

Which of the following is NOT a factor that contributes to the loss of functional diversity in urban areas?

  1. Habitat loss and fragmentation

  2. Pollution

  3. Climate change

  4. Increased species richness


Correct Option: D
Explanation:

Increased species richness, or the number of different species in an area, is not a factor that contributes to the loss of functional diversity in urban areas. In fact, it can actually increase functional diversity.

What are some of the consequences of losing functional diversity in urban areas?

  1. Reduced ecosystem resilience

  2. Increased susceptibility to invasive species

  3. Loss of ecosystem services

  4. All of the above


Correct Option: D
Explanation:

Losing functional diversity in urban areas can have a number of negative consequences, including reduced ecosystem resilience, increased susceptibility to invasive species, and loss of ecosystem services.

What can be done to mitigate the loss of functional diversity in urban areas?

  1. Protect and restore natural habitats

  2. Reduce pollution

  3. Promote sustainable land use practices

  4. All of the above


Correct Option: D
Explanation:

A combination of strategies is needed to mitigate the loss of functional diversity in urban areas, including protecting and restoring natural habitats, reducing pollution, and promoting sustainable land use practices.

What is the relationship between functional diversity and ecosystem functioning?

  1. Functional diversity has a positive effect on ecosystem functioning.

  2. Functional diversity has a negative effect on ecosystem functioning.

  3. Functional diversity has no effect on ecosystem functioning.

  4. The relationship between functional diversity and ecosystem functioning is unclear.


Correct Option: A
Explanation:

Functional diversity has been shown to have a positive effect on ecosystem functioning, such as increased productivity, stability, and resilience.

Which of the following is NOT an example of a functional trait?

  1. Body size

  2. Diet

  3. Habitat preference

  4. Species richness


Correct Option: D
Explanation:

Species richness is not a functional trait because it does not describe the role or function of a species in an ecosystem.

How can functional diversity be measured?

  1. By measuring the number of different species in an area.

  2. By measuring the abundance of each species in an area.

  3. By measuring the traits of each species in an area.

  4. By measuring the interactions between species in an area.


Correct Option: C
Explanation:

Functional diversity can be measured by measuring the traits of each species in an area, such as body size, diet, and habitat preference.

What is the difference between functional diversity and species diversity?

  1. Functional diversity is a measure of the variety of traits and functions performed by organisms in an ecosystem, while species diversity is a measure of the number of different species in an ecosystem.

  2. Functional diversity is a measure of the number of different species in an ecosystem, while species diversity is a measure of the variety of traits and functions performed by organisms in an ecosystem.

  3. Functional diversity and species diversity are the same thing.

  4. Functional diversity is a measure of the abundance of each species in an ecosystem, while species diversity is a measure of the number of different species in an ecosystem.


Correct Option: A
Explanation:

Functional diversity and species diversity are two different measures of biodiversity. Functional diversity focuses on the variety of roles and functions that different species play in an ecosystem, while species diversity simply counts the number of different species.

Why is functional diversity important for ecosystem functioning?

  1. Functional diversity increases the efficiency of resource use in an ecosystem.

  2. Functional diversity increases the stability of an ecosystem.

  3. Functional diversity increases the resilience of an ecosystem.

  4. All of the above


Correct Option: D
Explanation:

Functional diversity is important for ecosystem functioning because it increases the efficiency of resource use, the stability of an ecosystem, and the resilience of an ecosystem.

Which of the following is an example of a functional group?

  1. All plants that grow in a forest

  2. All animals that eat insects

  3. All birds that live in a city

  4. All fish that live in a river


Correct Option: B
Explanation:

A functional group is a group of organisms that share a common function or role in an ecosystem. All animals that eat insects are an example of a functional group because they all share the function of consuming insects.

How can functional diversity be used to manage ecosystems?

  1. By identifying and protecting keystone species.

  2. By promoting the establishment of new species.

  3. By controlling the abundance of invasive species.

  4. All of the above


Correct Option: D
Explanation:

Functional diversity can be used to manage ecosystems by identifying and protecting keystone species, promoting the establishment of new species, and controlling the abundance of invasive species.

What is the relationship between functional diversity and biodiversity?

  1. Functional diversity is a component of biodiversity.

  2. Biodiversity is a component of functional diversity.

  3. Functional diversity and biodiversity are the same thing.

  4. Functional diversity and biodiversity are unrelated.


Correct Option: A
Explanation:

Functional diversity is a component of biodiversity because it is a measure of the variety of roles and functions that different species play in an ecosystem.

Which of the following is NOT a threat to functional diversity?

  1. Habitat loss and fragmentation

  2. Climate change

  3. Pollution

  4. Increased species richness


Correct Option: D
Explanation:

Increased species richness is not a threat to functional diversity because it can actually increase the variety of roles and functions that different species play in an ecosystem.

What is the future of functional diversity in urban areas?

  1. Functional diversity is likely to increase in urban areas as cities become more sustainable.

  2. Functional diversity is likely to decrease in urban areas as cities become more dense and polluted.

  3. The future of functional diversity in urban areas is uncertain.

  4. Functional diversity is likely to remain the same in urban areas.


Correct Option: C
Explanation:

The future of functional diversity in urban areas is uncertain because it depends on a number of factors, such as the rate of urbanization, the policies that are put in place to protect biodiversity, and the impacts of climate change.
