Microcosm


Microcosm :

Artificial test system that simulates major characteristics of the natural environment for the purposes of ecotoxicological assessment: such a system would commonly have a terrestrial phase, with substrate, plants and herbivores, and an aquatic phase, with vertebrates, invertebrates and plankton. The term "mesocosm" implies a more complex and larger system than the term "microcosm" but the distinction is not clearly defined. Syn: experimental model ecosystem
