If one counts the aquaria in schoolrooms around the world and in the homes of hobbyists, probably millions of these microcosms have been set up, but relatively few have been seriously studied.

The study of these simplified ecosystems is providing provocative insights into ecological principles as well as issues of

Chemical Cycles and Limiting FactorsIf material is neither added nor lost, the principle of conservation of matter applies. An important part of ecosystem studies is chemical cycling, evaluating the storages of material, evaluating the main flows, and determining the processes controlling each pathway.
