What are the Classification of Ecosystem Services
Provisioning services
Regulating services
Supporting services
Cultural services
Ecosystem services that describe the material or energy outputs from ecosystems.
Provisioning services
The services that ecosystems provide by regulating the quality of air and soil or providing flood and disease control, etc.
Regulating services
These services underpin almost all other services. Ecosystems provide living spaces for plants or animals: they also maintain a diversity of plants and animals.
