What is the primary role of ecosystem services in ensuring food security and nutrition?

  1. Providing clean water for irrigation

  2. Regulating climate and weather patterns

  3. Supporting pollination and seed dispersal

  4. All of the above


Correct Option: D
Explanation:

Ecosystem services play a multifaceted role in supporting food security and nutrition by providing essential resources, regulating natural processes, and maintaining biodiversity.

Which ecosystem service is directly responsible for the availability of freshwater for irrigation?

  1. Water purification

  2. Nutrient cycling

  3. Climate regulation

  4. Pollination


Correct Option: A
Explanation:

Water purification is the ecosystem service that involves the removal of contaminants and pollutants from water sources, making it suitable for irrigation and other agricultural purposes.

How do ecosystem services contribute to regulating climate and weather patterns?

  1. By absorbing greenhouse gases

  2. By releasing oxygen into the atmosphere

  3. By influencing precipitation patterns

  4. All of the above


Correct Option: D
Explanation:

Ecosystem services play a crucial role in regulating climate and weather patterns through various processes, including carbon sequestration, oxygen production, and influencing precipitation patterns, which are essential for crop growth and food production.

Which ecosystem service is responsible for the transfer of pollen from one flower to another, enabling fertilization and seed production?

  1. Pollination

  2. Decomposition

  3. Nutrient cycling

  4. Water purification


Correct Option: A
Explanation:

Pollination is the ecosystem service that involves the transfer of pollen from the male anther of a flower to the female stigma, facilitating fertilization and the production of seeds, which are essential for food production.

How does nutrient cycling contribute to food security and nutrition?

  1. By replenishing soil fertility

  2. By supporting plant growth

  3. By enhancing crop yields

  4. All of the above


Correct Option: D
Explanation:

Nutrient cycling is the ecosystem service that involves the transformation and movement of nutrients through various components of the ecosystem, including soil, water, and organisms. It plays a vital role in replenishing soil fertility, supporting plant growth, and enhancing crop yields, ultimately contributing to food security and nutrition.

Which ecosystem service is responsible for the natural control of pests and diseases in agricultural systems?

  1. Biological control

  2. Water purification

  3. Climate regulation

  4. Pollination


Correct Option: A
Explanation:

Biological control is the ecosystem service that involves the use of natural enemies, such as predators, parasites, and pathogens, to regulate pest populations and reduce the incidence of diseases in agricultural systems, minimizing crop losses and enhancing food security.

How does biodiversity contribute to food security and nutrition?

  1. By providing genetic diversity for crop improvement

  2. By supporting ecosystem resilience

  3. By enhancing soil fertility

  4. All of the above


Correct Option: D
Explanation:

Biodiversity plays a crucial role in food security and nutrition by providing genetic diversity for crop improvement, supporting ecosystem resilience, enhancing soil fertility, and contributing to a variety of other ecosystem services that underpin food production.

Which ecosystem service is responsible for the decomposition of organic matter, releasing nutrients back into the soil?

  1. Decomposition

  2. Nutrient cycling

  3. Pollination

  4. Biological control


Correct Option: A
Explanation:

Decomposition is the ecosystem service that involves the breakdown of organic matter by microorganisms, releasing nutrients back into the soil, which are essential for plant growth and crop production.

How do ecosystem services contribute to sustainable agriculture?

  1. By reducing the need for chemical inputs

  2. By enhancing soil health

  3. By promoting biodiversity

  4. All of the above


Correct Option: D
Explanation:

Ecosystem services contribute to sustainable agriculture by reducing the need for chemical inputs, enhancing soil health, promoting biodiversity, and supporting other practices that minimize environmental impacts and ensure long-term food security.

Which ecosystem service is responsible for the formation and maintenance of fertile soils?

  1. Soil formation

  2. Nutrient cycling

  3. Water purification

  4. Climate regulation


Correct Option: A
Explanation:

Soil formation is the ecosystem service that involves the physical, chemical, and biological processes that lead to the development of fertile soils, which are essential for crop growth and food production.

How do ecosystem services contribute to the resilience of food systems?

  1. By providing a buffer against climate change impacts

  2. By supporting biodiversity

  3. By enhancing soil health

  4. All of the above


Correct Option: D
Explanation:

Ecosystem services contribute to the resilience of food systems by providing a buffer against climate change impacts, supporting biodiversity, enhancing soil health, and contributing to other factors that enable food systems to withstand shocks and stresses.

Which ecosystem service is responsible for the regulation of water flow and storage?

  1. Water regulation

  2. Climate regulation

  3. Pollination

  4. Biological control


Correct Option: A
Explanation:

Water regulation is the ecosystem service that involves the regulation of water flow and storage, including the absorption, retention, and release of water by ecosystems, which is essential for water availability and flood control.

How do ecosystem services contribute to the cultural and spiritual well-being of communities?

  1. By providing recreational opportunities

  2. By supporting traditional practices

  3. By enhancing aesthetic value

  4. All of the above


Correct Option: D
Explanation:

Ecosystem services contribute to the cultural and spiritual well-being of communities by providing recreational opportunities, supporting traditional practices, enhancing aesthetic value, and contributing to other factors that enrich the lives of people and communities.

Which ecosystem service is responsible for the regulation of air quality?

  1. Air purification

  2. Climate regulation

  3. Pollination

  4. Biological control


Correct Option: A
Explanation:

Air purification is the ecosystem service that involves the removal of pollutants and contaminants from the air, improving air quality and reducing the risk of respiratory illnesses.

How do ecosystem services contribute to the economic well-being of communities?

  1. By providing jobs and income

  2. By supporting tourism and recreation

  3. By enhancing property values

  4. All of the above


Correct Option: D
Explanation:

Ecosystem services contribute to the economic well-being of communities by providing jobs and income, supporting tourism and recreation, enhancing property values, and contributing to other factors that stimulate economic growth and development.
