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

  1. Genetic diversity

  2. Species diversity

  3. Ecosystem diversity

  4. Cultural diversity


Correct Option: D
Explanation:

Cultural diversity, while important for human society, is not a component of biodiversity, which focuses on the variety of life forms and their interactions within ecosystems.

What is the term used to describe the benefits that humans derive from ecosystems?

  1. Ecosystem services

  2. Biodiversity services

  3. Natural capital

  4. Environmental goods


Correct Option: A
Explanation:

Ecosystem services encompass the various benefits that humans obtain from ecosystems, such as clean air and water, food production, and climate regulation.

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

  1. Pollination

  2. Water purification

  3. Climate regulation

  4. Economic growth


Correct Option: D
Explanation:

Economic growth, while influenced by ecosystem services, is not directly considered an ecosystem service itself.

Biodiversity contributes to the resilience of ecosystems by:

  1. Increasing the number of species in an ecosystem

  2. Reducing the impact of environmental disturbances

  3. Promoting genetic diversity within species

  4. All of the above


Correct Option: D
Explanation:

Biodiversity enhances ecosystem resilience through a combination of factors, including increased species diversity, genetic diversity, and functional redundancy.

Which of the following is NOT a consequence of biodiversity loss?

  1. Reduced ecosystem productivity

  2. Increased vulnerability to pests and diseases

  3. Enhanced resilience to climate change

  4. Loss of cultural heritage


Correct Option: C
Explanation:

Biodiversity loss typically leads to reduced ecosystem resilience, making ecosystems more susceptible to the impacts of climate change.

The concept of keystone species refers to:

  1. Species that have a disproportionately large impact on their ecosystem relative to their abundance

  2. Species that are essential for maintaining ecosystem structure and function

  3. Species that are particularly vulnerable to environmental changes

  4. Species that are found in all ecosystems worldwide


Correct Option: A
Explanation:

Keystone species are those that play a critical role in maintaining the stability and functioning of an ecosystem, despite their relatively low abundance.

Which of the following is an example of a keystone species?

  1. Sea otters

  2. Wolves

  3. Bees

  4. All of the above


Correct Option: D
Explanation:

Sea otters, wolves, and bees are all examples of keystone species that play crucial roles in their respective ecosystems.

The loss of biodiversity can lead to:

  1. Reduced ecosystem productivity

  2. Increased pollution

  3. Climate change

  4. All of the above


Correct Option: D
Explanation:

Biodiversity loss has wide-ranging consequences, including reduced ecosystem productivity, increased pollution, and climate change.

Which of the following is NOT a strategy for conserving biodiversity?

  1. Protecting and restoring natural habitats

  2. Reducing pollution

  3. Promoting sustainable agriculture

  4. Introducing non-native species


Correct Option: D
Explanation:

Introducing non-native species can disrupt ecosystems and threaten native biodiversity, making it a counterproductive strategy for conservation.

The Convention on Biological Diversity (CBD) is an international agreement that aims to:

  1. Promote sustainable use of biodiversity

  2. Ensure fair and equitable sharing of benefits from biodiversity

  3. Reduce the rate of biodiversity loss

  4. All of the above


Correct Option: D
Explanation:

The CBD has three main objectives: to conserve biodiversity, to ensure the sustainable use of biodiversity, and to ensure the fair and equitable sharing of benefits arising from the use of genetic resources.

Which of the following is NOT a Millennium Development Goal (MDG) that is directly related to biodiversity?

  1. Eradicate extreme poverty and hunger

  2. Ensure environmental sustainability

  3. Promote gender equality and empower women

  4. Achieve universal primary education


Correct Option: D
Explanation:

While education is important for promoting sustainable development, it is not directly related to biodiversity conservation.

The concept of ecosystem services highlights the:

  1. Economic value of biodiversity

  2. Importance of biodiversity for human well-being

  3. Need to protect and restore ecosystems

  4. All of the above


Correct Option: D
Explanation:

The concept of ecosystem services emphasizes the economic, social, and environmental benefits that humans derive from ecosystems, highlighting the importance of biodiversity for human well-being and the need to protect and restore ecosystems.

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

  1. Food production

  2. Water supply

  3. Climate regulation

  4. Pollination


Correct Option: C
Explanation:

Climate regulation is considered a regulating ecosystem service, as it involves the regulation of climate patterns and processes.

Biodiversity plays a crucial role in:

  1. Maintaining ecosystem stability

  2. Supporting human health and well-being

  3. Mitigating climate change

  4. All of the above


Correct Option: D
Explanation:

Biodiversity contributes to ecosystem stability, supports human health and well-being through ecosystem services, and plays a role in mitigating climate change by regulating carbon dioxide levels and providing resilience to climate impacts.

The loss of biodiversity can have significant consequences for:

  1. Ecosystem functioning

  2. Human health and well-being

  3. Economic stability

  4. All of the above


Correct Option: D
Explanation:

Biodiversity loss can disrupt ecosystem functioning, leading to reduced ecosystem services, which can negatively impact human health and well-being, as well as economic stability.
