Which ecosystem service is an example of provisioning biodiversity services?

• A. Aesthetic value
• B. Food
• C. Climate regulation
• D. Pollination

Answer: (B)

Provisioning services are tangible goods produced by ecosystems. Biodiversity provides a variety of edible resources, so food is a direct product that comes from living systems. The other options describe either non-tangible values or ecological processes: aesthetic value is a cultural service (perception and experience), climate regulation is a regulating service, and pollination is an ecological process that enables plant reproduction and supports biodiversity and crop yields rather than being a direct product itself. Therefore, food best represents provisioning biodiversity services.
