Which of the following is an example of supporting services?

• A. Photosynthesis, biomass production, nutrient cycling, water balance, habitat provision
• B. Recreation
• C. Aesthetic experience
• D. Cultural heritage

Answer: (A)

Supporting services are the ecological processes that underpin how ecosystems function and enable all other services to occur. The option that lists photosynthesis, biomass production, nutrient cycling, water balance, and habitat provision is the best example because each element represents a fundamental function or structure that supports the rest of the ecosystem.

Photosynthesis captures energy and drives biomass production, forming the base of the food web. Nutrient cycling keeps nutrients available in the system, maintaining soil fertility and productivity over time. Water balance reflects how ecosystems regulate and supply water, which supports all living organisms and ecological processes. Habitat provision provides the physical space needed for species to live and interact, sustaining biodiversity that underpins resilience and service delivery.

The other options describe human experiences and uses, which are cultural services rather than the ecological processes that support ecosystem functioning.
