The figure 5 allow us to compare the impact of the addition of mesozooplankton with the functional trait of diapause on the dynamic of one trophic chain of the model. Figure 5A represent the total biomass of one diatom functional species and one microzooplankton in a simulation that do not exhibit the modifications needed to have surviving mesozooplankton. The figure 5B shows the total biomass of the same functional species in a simulation that do have a surviving mesozooplankton. We can observe that the addition of a surviving mesozooplankton feeding on the microzooplankton will release the functional diatom from the grazing pressure of that functional microzooplankton. Conversely, when the mesozooplankton will go into diapause, the microzooplankton will graze back on the functional diatom.
