Abstract: Cellular automata model was modified in order to take into account birthrates seasonal dependency and influence of water streams on movement of organisms. The model was verified within production-to-biomass and relative average quantity criteria and was used for investigation of pollution influence on population dynamic. Estimates of minimal pollution that leads to total death of organisms and of maximum pollution which influence is not observable within natural population dynamics are presented.

Keywords: self-organization, cellular automata, composition, population dynamic model, prey–predator system.
