It's clear from this article that different environmental conditions can favor one species of phytoplankton over another, with potentially major repercussions.

How could you modify the phytoplankton input parameters so that one species is favored (and thus more abundant) when nutrient levels are high, and the other species is favored when nutrient levels are low? (Type your response in the box below.)


To favor one species when nutrient levels are low, increase its K for nitrogen.
To favor the other species when nutrient levels are high, increase its growth rate (Growth0).
