Gregory is studying Lake Mairead. The lake has clear water and supports a healthy community of algae, fishes, and other aquatic
organisms. Gregory hypothesizes that phosphorus is a limiting nutrient in the lake. Which experimental result provides the strongest evidence in support of the hypothesis?
Through the process of Anthropogenic additions of N and P to the fresh water system can provide a strongest evidence for the above mentioned hypothesis.
Explanation:
As phosphorus is less mobile than nitrogen compounds, it is less likely to be found in fresh water where the organisms fail to access it. Phosphorus bounds mostly in the terrestrial ecosystem and in the aquatic matters because it has a sticky compound.
Thus it is a limited nutrient in freshwater lake like Mairead. However, this hypothesis can be different depending on other factors. Like, by adding anthropogenic N and P, this balance can be affected largely.
