Define ecosystem services and give two examples relevant to urban environmental management.

• A. Ecosystem services are the benefits humans receive from ecosystems; examples include provisioning water and regulating/supporting services such as air purification, flood control, and recreational value.
• B. Ecosystem services are only monetary profits from ecosystems; example is timber revenue.
• C. Ecosystem services are the physical structures in an ecosystem; example is rock formations.
• D. Ecosystem services are the biological diversity without any human benefits.

Answer: (A)

Ecosystem services are the benefits humans receive from ecosystems, including goods and functions that support our well-being. In urban environmental management, these services translate into practical benefits like a reliable water supply and reduced flood risk through green infrastructure, as well as improvements to air quality and spaces for recreation. The best choice fits because it recognizes that people gain tangible resources (water provisioning) and regulatory and cultural benefits (air purification, flood control, and recreational value) from ecosystems, which is exactly what ecosystem services aim to capture in urban contexts. Other options miss the concept by describing ecosystem services as purely monetary profits, as physical structures, or as biodiversity without any human benefits, which do not reflect the human-centered benefits these services provide.
