Document from the year 2016 in the subject Mathematics - Applied Mathematics, grade: 5.0, Lobachevsky State University of Nizhni Novgorod (Computational Mechanics), course: Applied Mathematics, language: English, abstract: This paper investigates and analyzes the behaviour of a herbivore-plankton continuous model. Two of the equilibrium points are solved analytically while the third equilibrium point is solved with the help of Nullclines phase portrait. The model’s equilibrium points stability and their ecological implications are analyzed and computer simulations are used to exhibit the characteristics of the model.
