Document Summary
The effects of nitrogen concentrations on autotroph concentrations in aquatic environments. In order to examine the effects of nitrogen concentrations on autotrophs in aquatic environments, zero, low, and high concentrations of nitrogen were placed in test tubes containing. The absorbance of the solutions within the tubes was tested each week in order to determine the chlamydomonas concentration. A four week experiment resulted in the low level of nitrogen leading to the greatest increase in. Chlamydomonas population size, followed by the high concentration of nitrogen. This rejected the null hypothesis and supported the alternative hypothesis, which stated the nitrogen concentrations do affect the growth rate of chlamydomonas populations in a controlled lab setting. The next part of this experiment involved using data collected from lsu"s university lake between 2008-2015 to test if nitrate concentrations had effected chlorophyll concentrations in the lake.
