The purpose of a chemical model of a lake is an accurate and concise description of the chemical processes taking place within the lake. A lake and its sediments represent an open system which interacts with its environment (that is, with the drainage basin and the atmosphere) in different ways by exchanging energy and matter. Since some of the most important chemical transformations in the system are linked to biological processes such as photosynthesis and decomposition, most chemical models include biological processes at least in the form of stoichiometric equations between organic matter and its decomposition products (see also Chapter 4).
