New Biotic Factor

So, my previous topic, and the topic that I wrote my application on, was The Effect of UV Radiation on Bluegreen Algae. I chose this topic because algae is the first link in the food chain, therefore it interested me because so many marine organisms, and ultimately terrestrial organisms depend on it. But, I won't be using this topic because someone in my class is already using it. Plus, Ms.Minn told me that algae would be too hard and not interesting enough. So, I'll be using Elodea instead. I still have to talk to Ms.Minn about what part of the photosynthesis we'll be using to measure such an carbon dioxide or oxygen. But, I'll still be using UV radiation as my independent variable. UV radiation, as the ozone thins, is becoming an important topic across the world because it is affecting countless organisms- marine and terrestrial. Hopefully this applies to Elodea.
