Abstract

In this paper, a non-linear mathematical model is proposed and analyzed to study the survival of a biological population (Plants, trees etc.) when it is affected by a toxicant (pollutant), emitted into the environment from external sources. It is shown that as the rates of emission and formation of a toxicant in the environment increases, the density of the plant population settles down to lower equilibria than their initial carrying capacity and their magnitude decreases as the equilibrium level of toxicant increases.
