Niche construction basically means that all organisms modify their environments. Our studies focused on how the cooperator and defectors interact through Prisoner’s Dilemma Games. We also focused on how the cooperators responded to the resources through niche constructions. Our system was solved by determining the equilibrium points and their stability by linearization, and the dynamical stable exit when the death rate is higher that the baseline birth rate, and the cooperation exist. Only the population of cooperation can be able to survive in this rough environment through niche construction, since we assume that only cooperator have the influence in the environment. But Defectors population cannot survive. Also the numerical simulations showed that, the assortment is a necessary condition for the evolution of cooperation in the ecological part.
