Modeling the survival and existence of a resource dependent population: Effects of toxicants emitted from external sources on the resource biomass

Abstract

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