What is functional redundancy?

  1. The ability of multiple species to perform the same ecological function

  2. The ability of a single species to perform multiple ecological functions

  3. The ability of a species to adapt to different environmental conditions

  4. The ability of a species to compete with other species for resources


Correct Option: A
Explanation:

Functional redundancy refers to the ability of multiple species to perform the same ecological function, such as pollination or seed dispersal.

What is functional compensation?

  1. The ability of a single species to perform multiple ecological functions

  2. The ability of a species to adapt to different environmental conditions

  3. The ability of a species to compete with other species for resources

  4. The ability of multiple species to perform the same ecological function


Correct Option: A
Explanation:

Functional compensation refers to the ability of a single species to perform multiple ecological functions, such as pollination and seed dispersal.

Which of the following is an example of functional redundancy?

  1. Two species of birds that both eat insects

  2. A species of bird that eats both insects and seeds

  3. A species of bird that migrates to different habitats depending on the season

  4. A species of bird that competes with other species for nesting sites


Correct Option: A
Explanation:

Functional redundancy refers to the ability of multiple species to perform the same ecological function, such as two species of birds that both eat insects.

Which of the following is an example of functional compensation?

  1. Two species of birds that both eat insects

  2. A species of bird that eats both insects and seeds

  3. A species of bird that migrates to different habitats depending on the season

  4. A species of bird that competes with other species for nesting sites


Correct Option: B
Explanation:

Functional compensation refers to the ability of a single species to perform multiple ecological functions, such as a species of bird that eats both insects and seeds.

What are the benefits of functional redundancy?

  1. It increases the stability of ecosystems

  2. It reduces the risk of species extinctions

  3. It allows for more efficient use of resources

  4. All of the above


Correct Option: D
Explanation:

Functional redundancy provides a number of benefits, including increased ecosystem stability, reduced risk of species extinctions, and more efficient use of resources.

What are the consequences of losing functional redundancy?

  1. It can lead to ecosystem collapse

  2. It can increase the risk of species extinctions

  3. It can reduce the efficiency of resource use

  4. All of the above


Correct Option: D
Explanation:

Losing functional redundancy can have a number of negative consequences, including ecosystem collapse, increased risk of species extinctions, and reduced efficiency of resource use.

What are some factors that can lead to the loss of functional redundancy?

  1. Habitat loss

  2. Pollution

  3. Climate change

  4. Invasive species


Correct Option:
Explanation:

A number of factors can lead to the loss of functional redundancy, including habitat loss, pollution, climate change, and invasive species.

What can be done to conserve functional redundancy?

  1. Protect habitats

  2. Reduce pollution

  3. Mitigate climate change

  4. Control invasive species


Correct Option:
Explanation:

A number of things can be done to conserve functional redundancy, including protecting habitats, reducing pollution, mitigating climate change, and controlling invasive species.

Why is functional redundancy important for the functioning of ecosystems?

  1. It provides resilience to environmental change

  2. It allows for more efficient use of resources

  3. It reduces the risk of species extinctions

  4. All of the above


Correct Option: D
Explanation:

Functional redundancy is important for the functioning of ecosystems because it provides resilience to environmental change, allows for more efficient use of resources, and reduces the risk of species extinctions.

Which of the following is an example of functional compensation in a forest ecosystem?

  1. A tree species that can tolerate both drought and flooding

  2. A bird species that can eat both insects and fruits

  3. A mammal species that can both climb trees and swim

  4. All of the above


Correct Option: D
Explanation:

Functional compensation in a forest ecosystem can be seen in a tree species that can tolerate both drought and flooding, a bird species that can eat both insects and fruits, and a mammal species that can both climb trees and swim.

How does functional redundancy contribute to the stability of ecosystems?

  1. It reduces the impact of environmental disturbances

  2. It allows for the maintenance of ecosystem functions even if some species are lost

  3. It promotes the coexistence of multiple species

  4. All of the above


Correct Option: D
Explanation:

Functional redundancy contributes to the stability of ecosystems by reducing the impact of environmental disturbances, allowing for the maintenance of ecosystem functions even if some species are lost, and promoting the coexistence of multiple species.

Which of the following is NOT a potential consequence of losing functional redundancy in an ecosystem?

  1. Increased vulnerability to environmental change

  2. Reduced efficiency of resource use

  3. Increased risk of species extinctions

  4. Enhanced ecosystem resilience


Correct Option: D
Explanation:

Losing functional redundancy in an ecosystem can lead to increased vulnerability to environmental change, reduced efficiency of resource use, and increased risk of species extinctions, but it does not enhance ecosystem resilience.

What is the relationship between functional redundancy and biodiversity?

  1. Functional redundancy is a measure of biodiversity

  2. Biodiversity is a measure of functional redundancy

  3. Functional redundancy and biodiversity are independent of each other

  4. Functional redundancy and biodiversity are positively correlated


Correct Option: D
Explanation:

Functional redundancy and biodiversity are positively correlated, meaning that ecosystems with higher biodiversity tend to have higher levels of functional redundancy.

Which of the following is an example of a management strategy that can promote functional redundancy in an ecosystem?

  1. Protecting habitats that support a variety of species

  2. Reducing pollution and other environmental stressors

  3. Encouraging the coexistence of multiple species

  4. All of the above


Correct Option: D
Explanation:

All of the above management strategies can promote functional redundancy in an ecosystem by protecting habitats, reducing environmental stressors, and encouraging the coexistence of multiple species.

How can functional redundancy be measured in an ecosystem?

  1. By calculating the number of species that perform the same ecological function

  2. By measuring the overlap in resource use among species

  3. By assessing the response of ecosystem functions to the loss of species

  4. All of the above


Correct Option: D
Explanation:

Functional redundancy can be measured in an ecosystem by calculating the number of species that perform the same ecological function, measuring the overlap in resource use among species, and assessing the response of ecosystem functions to the loss of species.
