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? a. filtering and removing phosphorus from a sample of lake water causes an increase in the growth of algae in the sample. b. adding phosphorus-rich fertilizer to a sample of lake water causes no observable effect. c. adding phosphorus-rich fertilizer to a sample of lake water causes an increase in the growth of algae. d. measurements show that phosphorus is more concentrated in bottom sediments than in the lake water.

The correct answer is option C.

Explanation:

Freshwater, like lakes, has less amount of phosphorous and aquatic animals, and organisms not able to access it in there. Phosphorous generally found in the terrestrial ecosystem.

Its less concentration makes it less concentration which is present in the aquatic matter as it is a sticky compound. So the growth of algae can be increase by adding phosphorus-rich fertilizer to a sample of lake water.

Thus, the correct answer is - option C.

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.

 An attempt to document and identify all biological species living in some defined area, usually a park, reserve, or research area. The numbers of species on earth is rapidly diminishing, knowing what species are around will give us an idea of what we're losing, how our actions are affecting the environment.
