Before revision: These interactions, assumed to be spatial homogeneous (and thus is termed a "zero-dimensional" model) are described in general terms as follows Rate of Change in P = (Nutrient uptake from N to P) minus (Mortality of P) minus (Grazing by Z) Rate of Change in Z = (Growth Efficiency) times (Grazing by Z) minus (Mortality of Z) Rate of Change in N = minus (Nutrient uptake from N to P) minus (1-Growth Efficiency) x (Grazing by Z) plus (Mortality of P) plus (Mortality of Z).
