Decomposition is the process by which dead plant and animal matter is broken down, releasing nutrients back into the environment.

Multiple choice

Which of the following is not an example of a supporting service?

  1. Soil formation

  2. Nutrient cycling

  3. Water cycling

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

Food production is a provisioning service, not a supporting service. Supporting services are the underlying processes that make it possible for provisioning, regulating, and cultural services to exist.

Multiple choice

What is the role of soil formation in supporting services?

  1. It provides a medium for plant growth.

  2. It stores water and nutrients.

  3. It helps to regulate the Earth's climate.

  4. All of the above.
