Answer:
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.
Explanation:
Answer: The higher animals needs and internal transport system so that the innermost cells can get nutrition which cannot be left on diffusion and osmosis to transmit. They also needed an internal transport system and so that they get oxygen to the internal cell...
