Final answer:
Wood from forests used for construction is an example of an ecosystem service as it is a benefit humans derive from healthy ecosystems.
Step-by-step explanation:
The question pertains to ecosystem services, which are the benefits provided by ecosystems that support and sustain human life and economic activity. Among the listed options, wood from forests used for construction is an example of an ecosystem service. This is because forests, a crucial component of the global ecosystem, purify air and water, generate oxygen, stabilize climate, and provide raw materials such as wood, which is used for construction and other purposes. Other ecosystem services include processes like the water cycle, removal of greenhouse gases, and the pollination of crops, all of which maintain environmental and human health.
