Behaviour of competitive model (38) around the equilibrium states. Declining population density associated with the competitive system is demonstrated in panels (a) and (b). As the resources declined, the two species compete for the limited resources, as evident in panel (b). Parameter values: (a) û = \( \widehat{v} \) =1, μ = φ = ψ = 0.5 at t = 5 and (b) û = \( \widehat{v} \) =1, μ = 0.5, φ = 0.15, ψ = 0.15 at t = 40. Other parameters are as in (b) except at \( \widehat{v} \) = 0.8, t = 40 for (c) and t = 20000 for (d)
