Question

ecosystem services are essential ecological processes that make life on earth possible. the annual estimated value of these services is $125 trillion.
what are some examples of ecosystem services?
□ intrinsic value of orangutans
□ pollination of crops by bees
□ scenic prairie vistas used for spiritual or educational purposes
□ sequestration of atmospheric carbon in rainforests
□ a colonizing population of sparrows evolving to survive in their new ecosystem

Explanation:

Ecosystem services are the benefits people obtain from ecosystems. Pollination by bees helps crop - production (provisioning service). Scenic prairie vistas for spiritual/educational use are cultural services. Carbon sequestration in rainforests is a regulating service. The intrinsic value of orangutans is not an ecosystem service in the traditional sense related to human - benefit from ecosystems. Sparrows evolving is a natural process not an ecosystem service directly providing benefits to humans.

Answer:

B. pollination of crops by bees
C. scenic prairie vistas used for spiritual or educational purposes
D. sequestration of atmospheric carbon in rainforests
