STOICHIOMETRIC MODELS OF ZOOPLANKTON NUTRITION
 
The relatively invariant elemental composition of many zooplankton supports the idea that they require a well-defined diet in order to meet their nutritional requirements. In contrast, prey items are highly variable; stoichiometric models, which balance elemental ratios in ingested food items with grazer biomass, provide a potentially useful means to describe zooplankton growth on heterogeneous prey. The rules of such models should, however, be examined carefully. Substrates are assimilated in the gut before use, and are then simultaneously consumed as building blocks for biomass and an energy source for respiration. A simple stoichiometric model of copepod nutrition will be presented. The usefulness of such models as a means of describing copepod nutrition will then be discussed.
