The paper presents the analysis of the Lotka-Volterra model with MM & S software. This software is designed based on the "Four Element Groups Concept" as well as on the "Change Rate Concept" and has been applied for analysis of different dynamic systems. A version of Lotka-Volterra model has been developed that includes 8 system elements: Two state elements (Predator population, Prey population), three constant elements (Predator zero isocline, Prey zero isocline, Prey capacity), one listed element (Disturbance), two intermediate elements (Prey related change of predator population, Predator related change of prey population). The simulation calculation has shown that in the case of a disturbance the system is putting backward from equylibrium but still tends to achieve equylibrium after that. Begon Michael, John L. Harper, Colin R. Townsend (1996) stated, that the coupled cycles of predator and prey populations exhibit neutral stability: They continue indefinitely if undisturbed, but each disturbance to a new abundance initiates a new, different series of neutrally stable cycles, around the same means but with a different amplitude. However, the investigations have shown that after a disturbance to a new abundance, the coupled cycles will become stable later with the same amplitude as before disturbance. The sensitivity analysis has shown that the dynamics of Predator and Prey populations are sensitive to changing value of Prey capacity.
