Stable and reproducible sealed complex ecosystems |
摘要 |
An apparatus and method for establishing a sealed ecological system that is self-sustaining, remains in dynamic equilibrium over successive generations of organisms. The wastes generated by one set of organisms are consumed entirely by other organisms as nutrients. This nutrient-waste balance is achieved by limiting the amounts of carbon, nitrogen, phosphorous and potassium present at the start-up of the system. Further stability and water clarity is achieved by the use of aquatic plants.
