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.

Adapted from Hartmut Bossel's "System Zoo 3 Simulation Models, Economy, Society, Development."

​Population model where the population is summarized in four age groups (children, parents, older people, old people). Used as a base population model for dealing with issues such as employment, care for the elderly, pensions dynamics, etc.
