An eco-column is used to model an ecosystem on a smaller scale. The purpose of an eco-column is to examine how an actual ecosystem would respond to different conditions. Eco-columns typically have three chambers: the aquatic chamber‚ decomposition chamber‚ and terrestrial chamber. The aquatic chamber contains water and an aquatic plant‚ and it is at the bottom of the eco-column. The decomposition chamber contains items that will work as decomposers and as a possible catalyst for plant growth. Examples
