Abstract

In this paper, a non-linear mathematical model is proposed and analyzed to study the existence and survival of a biological population when the resource and population is being affected by a toxicant (pollutant), emitted into the environment from external sources. Although the resource biomass density is also affected, here in the model we have only considered the adverse effects of biological population taking up the consideration of the uptake of toxicants by population
