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.
Self-sustainability is a type of sustainable living in which nothing is consumed other than what is produced by the self-sufficient individuals. Examples of attempts at self-sufficiency in North America include simple living, food storage, homesteading, off-the-grid, survivalism, DIY ethic, and the back-to-the-land movement.
The soils were selected to have enough carbon to provide for the plants of the ecosystems to grow from infancy to maturity, a plant mass increase calculated to be 20 short tons (18,000 kg). [56] The release rate of that soil carbon as carbon dioxide by respiration of soil microbes was an unknown that the Biosphere 2 experiment was designed to ...
Coral reefs are a largely self-sustaining ecosystem and up to 90% of the corals' nutrients may come from their symbiotic relationships. [7] The coral polyps and microscopic algae zooxanthellae in coral reefs have a symbiotic relationship wherein the algae provide nourishment to the coral polyps from within their tissue.
The bunker acts as its own ecosystem that provides everything humans need to survive -- and these students have committed to living in it for 200 days. China tests self-sustaining space station in ...
It is "self-sustaining" in comparison to systems which degrade much more quickly. The advantage of an aquarium closed with a lid (rather than a permanently sealed plug, which is found in the base of an EcoSphere) is that if the system goes out of equilibrium , the owner can remedy conditions and prevent a complete die-off.
The biosphere (from Ancient Greek βίος (bíos) 'life' and σφαῖρα (sphaîra) 'sphere'), also called the ecosphere (from Ancient Greek οἶκος (oîkos) 'settlement, house' and σφαῖρα (sphaîra) 'sphere'), is the worldwide sum of all ecosystems. It can also be termed the zone of life on the Earth.
