Tommy Frey ISP 217L 11/24/2007 Total Phosphorus vs. Dissolved Phosphorus Introduction Phosphorus is one of the essential elements required for all living things. Phosphorus can be found in DNA, RNA, and ATP, and also in bones, rocks, and even teeth. Phosphorus is highly reactive and can even be found in explosives. Phosphorus has no gaseous phase and is a limiting macro-nutrient, which means it is one of the least abundant macro-nutrients on earth. The availability of phosphorus can sometimes be problematic, especially in aquatic environments. When there is too much phosphorus this can create eutrophication to happen when causes the lake to have too much algae, and make the water murky. I believe that in this lab that there will be more total phosphorus in the water than dissolved phosphorus when the algae is present because the algae feeds on the dissolved phosphorus and then never excretes the dissolved oxygen back into the water. When the algae and Daphnia are present then I think that the total phosphorus will still be higher

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
