Concept:
Ecosystem services are the benefits that humans obtain from ecosystems. These are broadly classified into:
• Provisioning services
• Regulating services
• Supporting services
• Cultural services
Step 1: Understand provisioning services.
Provisioning services include all the products obtained directly from ecosystems such as:
• Food (fruits, crops, fish)
• Fresh water
• Timber and fiber
• Fuel and medicinal resources
These are essentially raw materials extracted from nature.
Step 2: Analyze the given options.
• (A) Provisioning → Direct raw materials from ecosystem \checkmark
• (B) Regulating → Climate control, flood regulation $\times$
• (C) Supporting → Nutrient cycling, soil formation $\times$
• (D) Cultural → Recreational, aesthetic values $\times$
Step 3: Conclusion.
Thus, raw materials extracted from ecosystems are called:

\text{Provisioning services}
