Abstract

This paper focuses on phase plane diagrams for two species ecological model comprising a mortal commensal and the host species with a constant harvesting of the commensal species. This model is characterized by a couple of first order non-linear ordinary differential equations. The possible three existing equilibrium points of the system are identified and the nature of the ecological interaction between the species is discussed based on the equilibrium points of the model equations through the phase plane diagrams for specific values to the parameters in the model equations.
