Which item is a typical provisioning service?

• A. Medicine
• B. Air quality improvement
• C. Habitat aesthetics
• D. Climate regulation

Answer: (A)

Provisioning services are tangible products obtained from ecosystems. Medicine fits this idea because many drugs come from natural resources—plants, fungi, microbes—that can be harvested or cultivated to produce medicines. The other options represent non-provisioning benefits: air quality improvement and climate regulation are regulating services that describe how ecosystems modify the environment, while habitat aesthetics is a cultural service tied to recreation and inspiration. So medicine is the typical provisioning service, a direct product derived from natural resources.
