The Biogeochemical Theatre — Phosphorus Cycling and Phosphorus Household in Lakes
Except for certain arid regions where lakes lose water only by evaporation, lakes are open flow-through systems whose content of a given element is determined by the dynamic balance between supply through the inflows, loss through the outflows, and internal sources and sinks. At sufficiently long timescales, the lake content of a given element tends to an equilibrium depending on the properties of both the lake and its catchment area. For dissolved substances that are unaffected by biological transformations (conservative elements), inflows and outflows can be different only in transient situations such as after a change in input concentration.
