While the food web showed here is a simple one, most feed webs are complex and involve many species with both strong and weak interactions among them (Pimm et al. 1991).

Abstract: Simple models, based on Lotka‐Volterra types of interactions between predator and prey, predict that enrichment will have a destabilizing effect on populations and that equilibrium ...
