"WebAll populations, from simple cellular to human, are dynamic systems. Any model for such a system has to be a kinetic model since one is dealing with rate processes (growth rate, birth rate, death rate, etc.). Such a model is very naturally described by a set of differ-ential equations analogous to that used in chemistry and physics to treat rate " - Population growth models and chemistry
