The purpose of this note is to mechanistically formulate amathematically tractable model that specifically deals with thedynamics of plant-herbivore interaction in a closedphosphorous (P) limiting environment. The key to our approach isthe employment of the plant cell P quota and the Droopequation for its growth. Our model takes the simple form of asystem of two autonomous ordinary di... https://www.thegreensjunglebeautyshops.shop/product-category/kids-sweater/
