We finished a lab on bioaccumulation and biomagnification by looking at actual specimens of marine and terrestrial ecosystems. Now finish the worksheet.
Your next exam, to be announced will cover the entire unit. It will be announced for after next week and I will ask you for your input so it does not conflict with your other exams. Since it is a unit exam, then I will give the option of not counting your biome exam if you do significantly better on this one.
