Abstract

Each biological species has its structure, which provides its existence in the atmosphere. But in the last few decades, there has been an abnormal change in their structure due to the externally emitted toxicant. These changes have a terrible impact on the atmosphere. In this prescribed model, we are proposing and analyzing the effect of externally emitted toxicants on a population model accompanied by the deformation delay and the delay in the depletion of toxicants. The dynamical nature and local stability of the model have been checked, and results show that during the absence of the deformation delay, the system is locally stable for toxicant delay at coexisting equilibrium points. But when both delays exist during the procedure, the biological population system becomes unstable,i.e., as the deformation delay increases, the system’s stability is distributed and reaches a critical value of deformation delay, and the system exhibits Hopf bifurcation. Finally, the numerical authentication of experimental results has been validated by the numerical simulation of the designed model
