Dynamical Analysis of a Nitrogen-Phosphorus-Phytoplankton Model

Figure 3

Bifurcation diagram of phytoplankton population with increasing input nitrogen concentration. The other parameters are the same as in Table 1. The red solid line indicates that exists and is globally asymptotically stable. The blue dashed line implies that exists, but is unstable. The green solid line indicates that exists and is globally asymptotically stable.
