All Lives Seek Balance Living organisms are living systems. Single organisms are living systems, but living systems can be of any size, from organism to community to ecosystem, to finally, the entire biosphere. The elements or parts of a living system include all the sub-systems it contains. These systems are organized and dynamically interact. A system includes its physical parts plus its relationship parts.
Living systems are self-regulating.
This is a major principle of ecology. Living organisms regulate their internal conditions to balance their interiors with their exterior environments. Inside and outside must fit. When this search for balance between inside and outside is successful, the living system survives. Homeostasis is a dynamic, active process, not a static one.
