Multiple choice

Which of the following is NOT an example of an ecosystem service that directly benefits human health?

  1. Clean air and water

  2. Pollination of crops

  3. Regulation of climate

  4. Decomposition of waste
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Decomposition of waste is a natural process that occurs in ecosystems, but it does not directly benefit human health. Clean air and water, pollination of crops, and regulation of climate are all examples of ecosystem services that directly benefit human health.

Multiple choice

Which ecosystem service is primarily responsible for regulating the Earth's climate?

  1. Carbon sequestration

  2. Water cycling

  3. Nutrient cycling

  4. Pollination
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Carbon sequestration is the process by which carbon dioxide is removed from the atmosphere and stored in plants, soils, and oceans. This process helps to regulate the Earth's climate by reducing the amount of greenhouse gases in the atmosphere.

Multiple choice

Which of the following is an example of an ecosystem service that is essential for human survival?

  1. Pollination of crops

  2. Regulation of climate

  3. Provision of food and water

  4. Decomposition of waste
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The provision of food and water is an essential ecosystem service for human survival. Without food and water, humans would not be able to survive.

Multiple choice

Which of the following is an example of a provisioning ecosystem service?

  1. Pollination of crops

  2. Regulation of climate

  3. Provision of food and water

  4. Decomposition of waste
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Provisioning ecosystem services are the material benefits that people derive from ecosystems. Provision of food and water is an example of a provisioning ecosystem service.

Multiple choice

Which of the following is an example of a regulating ecosystem service?
