From: Comparison and analysis of two forms of harvesting functions in the two-prey and one-predator model
The changes of the biomass of system species and the yield. (a) Prey \(x_{1}\) biomass varies with \(E_{1}\) and \(E_{2}\). (b) Prey \(x_{2}\) biomass varies with \(E_{1}\) and \(E_{2}\). (c) The predator biomass varies with \(E_{1}\) and \(E_{2}\). (d) The yield from both prey and predator as function of \(E_{1}\) and \(E_{2}\). The relevant parameters except \(d=0.4\), \(\sigma=0.0035\) are given in (7.1) and \((k_{1}, k_{2})=(200, 300)\)
