Figure 3.1 and 3.2 shows that the solution of this system initially oscillates
but eventually tends to the stable nontrivial equilibrium solution. As shown in Figure
3.2 (a) and (b), the result shows that biomass density of jellyfish is less than those of
zooplankton whereas when the intrinsic growth rate of zooplankton increased to 3, the
result from Figure 3.2 (c) shows that biomass density of jellyfish is less than those of
zooplankton up until the time of 20 unit, then the biomass density of jellyfish becomes
more than those of zooplankton.
