The system comprises of a commensal (S1) common to two hosts S2 and S3. S2 is a commensal of S3 and S3 is a host of both S1, S2. Further the first and second species have unlimited resources while the third has limited resources. The basic equations for this model constitute as three first order non-linear coupled ordinary difference equations. All possible equilibrium points are identified based on the model equations at two stages and criteria for their stability are discussed. Further the numerical solutions are computed for specific values of the various parameters and the initial conditions.
