Question

which resource is a direct ecosystem service
biodiversity
fresh water
photosynthesis
land development

Answer 1

Fresh water is a direct ecosystem service. It is provided by ecosystems and can be directly used by humans and other organisms for drinking, agriculture, and sanitation, among other needs. In contrast, biodiversity and photosynthesis are both essential processes that contribute to ecosystem functioning but are not direct services that can be consumed or used immediately. Land development, on the other hand, is a human activity rather than an ecosystem service.
