To create a completely self-sustaining ecosystem, you need to use an airtight container. Some people use vases, others use Mason jars, and there have even been some using old pickle jars, like the ...
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 ...
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.
