Abstract

The present paper explores a tri-trophic food chain model with three species and harvesting in prey with complex dynamics. Here we
 discuss the HP model and Holling type-II function. We nd the Extinction criteria of species and boundedness . We also derived the co dition of existence and stability of equilibrium points. To investigate  the local stability and Hopf-bifurcation. Also discuss the Permanence and Impermanence of the system for future time. In the complex dynamical system we observed stable focus, limit cycle, period doubling and chaotic dynamics of the system. We observe that chaotic oscillations in a tri-trophic food chain model is common and control of such oscillation is utmost important from ecological as well as economical  viewpoint.
