Ecological restoration aims to:

  1. Restore degraded ecosystems to their natural state

  2. Enhance biodiversity in existing ecosystems

  3. Create new ecosystems from scratch

  4. All of the above


Correct Option: D
Explanation:

Ecological restoration encompasses a wide range of activities aimed at restoring degraded ecosystems, enhancing biodiversity, and creating new ecosystems.

Which of the following is NOT a common method used in ecological restoration?

  1. Reforestation

  2. Revegetation

  3. Bioremediation

  4. Invasive species removal


Correct Option: C
Explanation:

Bioremediation is a process that uses microorganisms to clean up contaminated environments, while reforestation, revegetation, and invasive species removal are all common methods used in ecological restoration.

Biodiversity conservation is important because it:

  1. Provides ecosystem services

  2. Maintains ecological balance

  3. Enhances resilience to environmental changes

  4. All of the above


Correct Option: D
Explanation:

Biodiversity conservation provides a wide range of benefits, including ecosystem services, ecological balance, and resilience to environmental changes.

Which of the following is NOT a key component of biodiversity?

  1. Species diversity

  2. Genetic diversity

  3. Ecosystem diversity

  4. Functional diversity


Correct Option: C
Explanation:

Ecosystem diversity refers to the variety of ecosystems found in a region, while species diversity, genetic diversity, and functional diversity are all key components of biodiversity.

Ecological restoration can help to mitigate the effects of:

  1. Climate change

  2. Pollution

  3. Habitat loss

  4. All of the above


Correct Option: D
Explanation:

Ecological restoration can help to mitigate the effects of climate change, pollution, and habitat loss by restoring degraded ecosystems and enhancing biodiversity.

Which of the following is NOT a benefit of ecological restoration?

  1. Improved water quality

  2. Increased carbon sequestration

  3. Enhanced resilience to natural disasters

  4. Reduced soil erosion


Correct Option: B
Explanation:

Ecological restoration can improve water quality, increase resilience to natural disasters, and reduce soil erosion, but it does not directly lead to increased carbon sequestration.

Biodiversity enhancement involves:

  1. Introducing new species to an ecosystem

  2. Increasing the abundance of existing species

  3. Improving the genetic diversity of a species

  4. All of the above


Correct Option: D
Explanation:

Biodiversity enhancement involves a combination of introducing new species, increasing the abundance of existing species, and improving the genetic diversity of a species.

Which of the following is NOT a common threat to biodiversity?

  1. Habitat loss

  2. Pollution

  3. Climate change

  4. Overexploitation


Correct Option: D
Explanation:

Overexploitation refers to the excessive use of resources, while habitat loss, pollution, and climate change are all common threats to biodiversity.

Ecological restoration projects often involve:

  1. Planting native trees and shrubs

  2. Removing invasive species

  3. Restoring wetlands

  4. All of the above


Correct Option: D
Explanation:

Ecological restoration projects often involve a combination of planting native trees and shrubs, removing invasive species, and restoring wetlands.

Biodiversity conservation and enhancement are important for:

  1. Maintaining ecosystem health

  2. Ensuring food security

  3. Providing clean air and water

  4. All of the above


Correct Option: D
Explanation:

Biodiversity conservation and enhancement are important for maintaining ecosystem health, ensuring food security, and providing clean air and water.

Which of the following is NOT a common method used for biodiversity enhancement?

  1. Assisted migration

  2. Genetic engineering

  3. Habitat restoration

  4. Reintroduction of native species


Correct Option: B
Explanation:

Genetic engineering is not a common method used for biodiversity enhancement, while assisted migration, habitat restoration, and reintroduction of native species are all common methods.

Ecological restoration can help to improve:

  1. Water quality

  2. Air quality

  3. Soil health

  4. All of the above


Correct Option: D
Explanation:

Ecological restoration can help to improve water quality, air quality, and soil health.

Biodiversity conservation and enhancement are essential for:

  1. Sustainable development

  2. Human well-being

  3. Both of the above


Correct Option: C
Explanation:

Biodiversity conservation and enhancement are essential for sustainable development and human well-being.

Which of the following is NOT a key factor to consider when planning an ecological restoration project?

  1. The type of ecosystem being restored

  2. The goals of the restoration project

  3. The availability of resources

  4. The political climate


Correct Option: D
Explanation:

The political climate is not a key factor to consider when planning an ecological restoration project, while the type of ecosystem being restored, the goals of the restoration project, and the availability of resources are all important factors to consider.

Ecological restoration and biodiversity conservation are important for:

  1. Mitigating climate change

  2. Protecting endangered species

  3. Ensuring food security

  4. All of the above


Correct Option: D
Explanation:

Ecological restoration and biodiversity conservation are important for mitigating climate change, protecting endangered species, and ensuring food security.
