System Zoo Z404 Prey and two Predator Populations from Hartmut Bossel (2007) System Zoo 2 Simulation Models. Climate, Ecosystems, Resources

Often a single prey population is the source of food for several  competing predators (e.g. mice as prey of foxes and birds of prey)​. Here again a reliable intuitive assessment of long-term development resulting from the particular system relationship is impossible. A simulation model can assist in recognizing development trends inherent in the system structure even if in reality a variety of other factors determine the development and may cause it to proceed on a somewhat different path.
