Webthe mesopredator release hypothesis, then, we can look to ecological theory for insight into whether strong top-down effects might be ex- pected for the top predator/mesopredator/land- bird system. Little integration of the MRH and trophic cascade literatures has occurred as yet. WebKey points. Predation is an interaction in which one organism, the predator, eats all or part of the body of another organism, the prey. Herbivory is a form of predation in which the prey organism is a plant. Predator and prey populations affect each other's dynamics. The sizes of predator and prey populations often go up and down in linked cycles.
