microcosm

https://doi.org/10.1351/goldbook.14852
Artificial multi-species test system that simulates major characteristics of the natural environment for the purposes of ecotoxicological effects and risk assessment; such systems are normally terrestrial or aquatic and may contain plants, animals (vertebrates and invertebrates), and microorganisms.
Note: The terms mesocosm and macrocosm are used to refer to larger and more complex systems than microcosms, but the distinction is often not clearly defined.
