Which ecosystem services are defined as the processes that keep ecosystems healthy?

The ecosystem services that are defined as the processes that keep ecosystems healthy are known as "supporting services". These include services such as nutrient cycling, soil formation, primary production, and habitat provision. These services are fundamental as they maintain the conditions for life on Earth. They underpin all other ecosystem services by maintaining the healthy functioning of all ecosystems, and are thus crucial for the survival of all species, including humans.
