From the Greek, meaning 'standing still'. Homeostasis relates to a system which achieves a consistent state through internal regulation. This concept applies to both open and closed systems, and is used to express a state whereby the system remains in balance. This is a particularly relevant concept in terms of open systems, where new elements may apply to these systems. In these cases homeostasis relates to an important factor in the structure of the systems.
Examples of Homeostasis:
Gaia Theory: The homeostasis concept for Earth is based on the natural regulation of the biosphere.|
Ecology: Islands have a form of homeostasis based on ecological regulators.
