Regulating
Explanation:
According to Millennium Ecosystem Assessment, there are four major categories of ecosystem services. These services include:
1. Provisioning
2. Regulating
3. Supporting
4. Cultural
The Regulating category is the category that consists of Air and water quality - Purification, climate, erosion, disease transmission, and pest proliferation - Biological control, and pollination. 
The ecosystem services are services or functions rendered by the natural environment that ensure the environment is sustainable and healthy for human use.
