This paper intends to investigate the global stability of a mathematical model of an ecological Ammensal model with Four Species (A,P,E,H)Eco-System of Ammensal-Prey(A),Predator-Ammensal(P),Enemy-Ammensal(E) and malice(M) species.This model is formed by establishing the System of an Ammensal –prey(A) , a Predator –Ammensal(P) that endures on Ammensal –prey(A), enemy-Ammensal(E) and malice(M) for which A, P are Ammensal respectively i.e., E and M adversely effect on A and P without themselves getting effected in any manner. Further E is Ammensal for M and M harms for E..The three levels of Ammensalism are comprised in the pairs of (A, E), (P, H) and (E,H). The model is constituted with a set of four first order non-linear ordinary differential coupled equations.In this model, sixteen equilibrium points are obtained. Global stabiliy of this model is ascertained in the normal steady state.
Keywords: Ammensal, Prey, Predator, Enemy, Malice, Eco-System, Equillibrium point, stable.
