Two species of zooplankton (Daphnia and Bosmina) are both limited by the availability of their food (phytoplankton). When grown without Daphnia, Bosmina reaches an equilibrium density of 1000 individuals/liter and drives phytoplankton concentrations down to 30 cells/ml (i.e., at [phytoplankton]>30 cells/ml, Bosmina shows positive growth). In the absence of Bosmina, Daphnia reaches a density of 50 individuals/liter and drives phytoplankton concentrations down to 10 cells/ml. You now grow Daphnia and Bosmina together. Assume they remain limited by phytoplankton.
