Persistence of a four species food chain with full omnivory.
We consider here a food chain composed of four species with full omnivory with Lotka-Volterra dynamics. Conditions for uniform persistence and weak persistence of the food chain are derived. It is also shown that the system exhibits a heteroclinic cycle.
