In this report, we will investigate two types of food-predator systems with functional response. Functional response describes how the rate of prey consumption by predators changes with the abundance of prey. The first type of food-predator system we will consider is the Holling-Type II functional response, also known as the sigmoidal functional response. The second type is the Beddington-DeAngelis functional response, which incorporates a term for the saturation of predator growth rate as the predator population increases. Objective:The main objective of this report is to investigate the qualitative properties and Hopf bifurcation of these two food-predator systems with functional response. Qualitative properties refer to the stability of the system, the existence and stability of equilibria, the presence of limit cycles, and other dynamic behaviors. Hopf bifurcation is a type of bifurcation in which the system undergoes a qualitative change in its dynamics as a parameter is varied, resulting in the appearance of a limit cycle.Methodology:To investigate the qualitative properties and Hopf bifurcation of the two food-predator systems, we will use mathematical modeling and analysis techniques. We will begin by formulating the dynamical equations that describe the interactions between the prey and predator populations. We will then linearize the system near the...
