Is an example of self regulating ecosystem?

Negative feedback operates at sublevels in ecosystems. For example, when nutrient release exceeds a certain level, negative feedback inhibits further release or when a population attains enormous size, various events are started that control reproduction. Thus, ecosystems are self- regulating entities.
