Ecology is from Greek oikos logos, study of a household. The English word means study of management. Most people don't know that, they assume it means trees and bugs and stuff. Ecosystem is a recently made up word meaning any community of interacting things and their environment. Most people have no clue what it means.
"Ecosystem services are grouped into four broad categories: provisioning, such as the production of food and water; regulating, such as the control of climate and disease; supporting, such as nutrient cycles and crop pollination; and cultural, such as spiritual and recreational benefits."
