Closed ecological systems or contained ecological systems (CES) are ecosystems that do not rely on matter exchange with any part outside the system. The term is most often used to describe small, man-made ecosystems. Such systems can potentially serve as a life-support system or space habitats. [1]
A closed platform, walled garden, or closed ecosystem [1] [2] is a software system wherein the carrier or service provider has control over applications, content, and/or media, and restricts convenient access to non-approved applicants or content.
Controlled (or closed) ecological life-support systems (acronym CELSS) are a self-supporting life support system for space stations and colonies typically through controlled closed ecological systems, such as the BioHome, BIOS-3, Biosphere 2, Mars Desert Research Station, and Yuegong-1.
An ecosystem (or ecological system) is a system formed by organisms in interaction with their environment. [2]: 458 The biotic and abiotic components are linked together through nutrient cycles and energy flows. Ecosystems are controlled by external and internal factors.
Research on closed ecosystems was initiated by Vladimir Vernadsky's 1926 book The Biosphere and Konstantin Tsiolkovsky in the 1950s and 1960s in Russia, culminating in the manned closed BIOS-3 facility, a 315 cubic meter habitat located at the Institute of Biophysics, Krasnoyarsk, Siberia. Frieda Taub reviewed work from 1953 to 1974. [3]

A holistic community (also referred to as closed or unitary community) is an ecosystem where species within the community are interdependent, relying on each other to maintain the balance and stability of the system.
Diagram of a small form closed system mesocosm. Different components of a successful mesocosm . A mesocosm (meso-or 'medium' and -cosm 'world') is any outdoor experimental system that examines the natural environment under controlled conditions. In this way mesocosm studies provide a link between field surveys and highly controlled laboratory ...
