摘要: A nonlinear mathematical model to study the effect of density human population on depletion dissolved oxygen in a water body is proposed and analyzed. The governed by interactions among five dependent variables, namely resource biomass, population, concentration organic pollutants, bacteria oxygen. In formulation, it assumed that biomass follow logistic models with prey--predator type interaction. analyzed using stability theory differential equations. analysis shows increase intensify body. Numerical simulations are carried out illustrate analytical findings.
