Oxygen is essential for all plants and animals to survive, whether they live on the land or in the water. Aquatic species rely on oxygen that is dissolved in the water (DO). If water is polluted because of discharge of pollutants or the water body acquires a high level of concentration of nutrients resulting excessive growth of algae (the process is called Eutrophication), due to which the level of dissolved oxygen decreases to support their lives. To analyze this ecological problem a conceptual and mathematical model is proposed. This model consists of set of nonlinear differential equations with boundary conditions. After obtaining the solution of these equations it is important to study about the stability of the solution by using stability theory.
