A dynamic state of a closed ecosystem and its significance to the generation of the Earth's environment.
The Earth forms a living-system composed of large materially closed ecosystems (CES). We are performing various experiments to study comparable living-systems, especially smaller samples we call "microcosmic type CES". CES have an ability to persist despite perturbation. We show experimental results of the behavior of CES mainly during the transition form a semi-open state to an entirely closed one. We report phenomena on CES instability which may be inherent in them. We suggest that CES possess some properties that may help elucidate the nature of the Earth as a living system. Climatic change on the Earth, such as oceanic anoxia and its consequences, may have been due to disturbances as modeled in a CES.
