Your biology professor takes the class on a field trip to a local lake. As you get out of the van, the professor hands you a notebook and a field test kit. Your assignment is to spend an hour studying the lake and writing down all observations. At the end of the hour, the professor asks you to hypothesize if the lake is eutrophic or oligotrophic. Looking at the observations you recorded, you hypothesize the lake is oligotrophic. Which of the following observations support your hypothesis? Check all that apply.
