The dependence of systems on a lower level of complexity in relation to higher level ones in organizations or ecosystems.
This is a characteristic relation in hierarchic systems, where lower levels of organization depend on regulations and controls by higher levels.
More generally, any system or subsystem finds itself within a relation of asymmetrical dependence in relation to its environment or suprasystem. Even if and when it is able to modify its environment in a way more suitable to its necessities. such possibilities are limited by its archetypical survival needs.
It should be noted however that higher levels are also dependent of the lower ones, which provides them with the basic inputs they need in order to exert their roles as regulators, controllers and deciders.
