Abstract: The Present investigation is an analytical study of a three species syn-ecological model which comprises three species. Here first species (N1) ammensal on the second (N2), second species ammensal on the third (N3). In this model first species (N1) and third species (N3) are neutral to each other. And first (N1) and second species (N2) are harvested at a rate proportional to their population sizes. All possible equilibrium points are identified and the stability of Interior equilibrium point is discussed by using Routh-Hurwitz criteria and the solutions are carried out. Further the global stability of the system is discussed by constructing a suitable Lyapunov function. The analytical results are supported by numerical simulation using Mat Lab.
Keywords: Ammensal, Neutral, Equilibrium Points, Lyapunov’s function and Routh-Hurwitz criteria.
