  2. Pollination

  3. Food

  4. Water purification
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Food is a provisioning ecosystem service because it provides us with sustenance and energy.

Multiple choice

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

  1. Soil formation

  2. Nutrient cycling

  3. Biodiversity

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Soil formation, nutrient cycling, and biodiversity are all examples of supporting ecosystem services because they provide the foundation for all other ecosystem services.

Multiple choice

Which type of ecosystem service is most directly related to human health?

  1. Provisioning services

  2. Regulating services

  3. Cultural services

  4. Supporting services
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Regulating services, such as clean air and water, are most directly related to human health because they help to protect us from disease and other health problems.

Multiple choice

Which type of ecosystem service is most directly related to economic activity?

  1. Provisioning services

  2. Regulating services

  3. Cultural services

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

Provisioning services, such as food, water, and timber, are most directly related to economic activity because they provide the raw materials that we use to produce goods and services.

Multiple choice

Which type of ecosystem service is most directly related to human well-being?

  1. Provisioning services

  2. Regulating services

  3. Cultural services

  4. Supporting services
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Cultural services, such as recreation, inspiration, and education, are most directly related to human well-being because they provide us with non-material benefits that enrich our lives.

Multiple choice

Which type of ecosystem service is most directly related to the functioning of ecosystems?

  1. Provisioning services

  2. Regulating services

  3. Cultural services

  4. Supporting services
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Supporting services, such as soil formation, nutrient cycling, and biodiversity, are most directly related to the functioning of ecosystems because they provide the foundation for all other ecosystem services.

Multiple choice

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

  1. Food

  2. Water

  3. Climate change

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

Multiple choice

Which of the following is NOT a major factor contributing to the biodiversity of coral reef ecosystems?

  1. Habitat complexity

  2. Symbiotic relationships

  3. Genetic diversity

  4. Competition
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Competition is not a major factor contributing to the biodiversity of coral reef ecosystems, as these ecosystems are characterized by a high degree of cooperation and mutualism among species.

Multiple choice

Which of the following is NOT a key nutrient cycle in ecosystems?

  1. Carbon Cycle

  2. Nitrogen Cycle

  3. Phosphorus Cycle

  4. Oxygen Cycle
Reveal answer Fill a bubble to check yourself
D Correct answer
