Extinction for a discrete competition system with the effect of toxic substances

Abstract

A nonautonomous discrete competitive system with nonlinear inter-inhibition terms and one toxin producing species is studied in this paper.Sufficient conditions which guarantee the extinction of one of the components are obtained and the global attractivity of the other one is proved.Our results supplement some existing ones.Numerical simulations show the feasibility of our results.
