Ecosystem services classification. Download the latest spreadsheet of the CICES classification at www.cices.eu . Consider the Section->Division->Group->Class hierarchy developed. Please answer the following questions:

6.a. Recall the recent news about the discovery of a worm capable of digesting Styrofoam (https://news.stanford.edu/pr/2015/pr-worms-digest-plastics-092915.html ). Suppose these worms are used directly to process Styrofoam waste. Classify this service by Section->Division->Group->Class.

6.b. Now suppose scientists use the genetic information from the microorganisms in these worms to develop an industrial-scale cleanup process. How would the ecosystem service be classified then?

6.c. Is natural gas classified as an ecosystem service in CICES?

6.d. A farmer installs a riparian buffer strip near a stream. What ecosystem service is he enhancing?

6.e. You go on an orca-watching tour near San Juan islands. What ecosystem service did you enjoy?

Or at the end of please provide conclusion:-
