A Series Solution of Ecological Ammensalism With Four Species at Three Levels

Abstract

In this paper, a special Syn ecological model is considered with four species. Those are Ammensal-Prey(A),Predator-Ammensal(P),Enemy-Ammensal and Malice(M) at three levels of  ammensal interactions. This model is constructed by a set of four first order non-linear ordinary differential coupled equations. Homotopy Perturbation method is applied on this model to gain the series solution.
