Volterra has argued that the coexistence of two or more predators competing for fewer prey resources is impossible, which was later known as the principle of competitive exclusion. The principle of competitive exclusion was reexamined by Koch [1] in 1974 who found via numerical simulation that the coexistence of two predators competing exploitatively for a single prey species in a constant and uniform environment was in fact possible when the predator functional response to the prey density was assumed according to nonlinear function, and such coexistence occurred along what appeared to be a periodic orbit in the positive octant of [R.sup.3] rather than an equilibrium.
In this paper, we study the principle of competitive exclusion associated with system (2).
The classical principle of competitive exclusion postulates that if two species compete for the same limited resource, they cannot coexist.
