Biology Assignment: Help

Postby ineedyourhelpplease » Sun Mar 29, 2009 4:24 am

I have a writing assignment due on Tuesday and am having a lot of trouble putting this data together. I have to compare nitrate levels with autotrophs present (or dissolved oxygen levels) in a few lakes and a bayou. I can either use the data from all of them, or one of them. I don't see a point in doing a select few, unless you guys think it's okay. My peers told me that nitrate levels are inversely correlated with autotrophic levels, but my data is not being consistent whatsoever. What I did do was record the Net Primary Production of oxygen to correspond to the autrophic levels. Is this the problem with my project? I can't seem to wrap my head around the idea that nitrate levels have nothing to do with autotrophic levels, because both my peers and instructor said it has an effect on each other in SOME way. So, will Gross Primary Production or Respiration (amount of energy used by community) be a more direct measurement of the amount of autotrophs present? Or was Net Primary Production the best measurement? If anyone is willing to help me with this entire thing one-on-one I would GREATLY appreciate it.

yes, your data should show increase in nitrate levels =more autotrophs present

And I think you should use data from all of them for comparision.

pS: R you considering other factors such as aeration?
