Simulations in a Plankton Model

A technique for analyzing the stability of a zooplankton, phytoplankton, nutrient interaction model is described. This is an extension of a two-dimensional predator-prey model, incorporating a nutrient food source. In this study difference equations, rather than differential equations, are used to simulate the system since the systems are more easily studied in this formulation. Using only a few reasonable constraints on the system, a remarkable stability is obtained.
