In аn effоrt tо understаnd cаuses оf algal blooms in coastal Rhode Island, researchers conducted an experiment in estuarine mesocosms. They set up 8 mesocosms, 2 replicates of each treatment (see table with treatments below). After several weeks, they measured chlorophyll a (as a measure of algal productivity). This is a preliminary study, but for our purposes, let's assume the differences across treatments are real. Abbreviation Treatment C No nutrients added. N Nitrogen added. P Phosphorus added NP Nitrogen and Phosphorus added Here is a graph of the results. Given the above data, it would be reasonable to conclude that [limiting] in this system. Based on what you know about N and P cycles, the forms of N and P added to the mesocosms for this experiment were likely [nandp]. The ecological problem they are probably trying to address is [ecologicalproblem].
