Ecosystem provides us food, raw materials, genetic resources. This is a close example of \(\underline{\hspace{3cm}}\).
Show Hint
To remember the types of ecosystem services, think of them this way:
- Provisioning = Products (food, water, wood)
- Regulating = Processes (climate control, cleaning water)
- Cultural = People (recreation, spirituality)
- Supporting = Foundation (photosynthesis, soil formation)
Step 1: Understanding the Concept:
Ecosystem services are the many and varied benefits to humans provided by the natural environment and from healthy ecosystems. They are categorized into four main types. The question asks to categorize tangible products we get from ecosystems.
Step 3: Detailed Explanation:
The four categories of ecosystem services are:
\[\begin{array}{rl} \bullet & \text{(D) Provisioning services: These are the tangible products obtained from ecosystems. This category includes food (crops, fish), fresh water, raw materials (wood, fiber), and genetic resources. The items listed in the question—food, raw materials, genetic resources—are all direct products.} \\ \bullet & \text{(A) Regulating services: These are the benefits obtained from the regulation of ecosystem processes, such as climate regulation, flood control, and water purification.} \\ \bullet & \text{(B) Supporting services: These are the services necessary for the production of all other ecosystem services. Examples include nutrient cycling, soil formation, and primary production. They are the underlying processes.} \\ \bullet & \text{(C) Cultural services: These are the non-material benefits people obtain from ecosystems, such as spiritual enrichment, recreation, and aesthetic experiences.} \\ \end{array}\]
Step 4: Final Answer:
Providing food, raw materials, and genetic resources is a classic example of provisioning ecosystem services.
