Nitrogen, Phytoplankton 1, Phytoplankton 2
Add Phytoplankton#2 as a component (and de-select any other components if they are still selected). Run the model and compare the ecosystem with one and two phytoplankton taxa.
If the two phytoplankton taxa have the same settings, each will grow equally and use up half of the nitrogen. If the phytoplankton have different settings, they will compete against each other for resources (nitrogen and light) and one will do better than the other. We will discuss the phytoplankton settings and their effect later, in the Sensitivity Experiments.
