More Nutrient Cycles

Wednesday, we skimmed over a reading, Nutrient Cycles, that won't be fully due until after Halloween, unless people are not too busy with their projects. We watched two slideshows that follow an Oxygen atom through a food web in a forest ecosystem and a Phosphorus atom through a forest and pond ecosystem. You can check those out here: Oxygen slideshow and Phosphorus slideshow. We revisited the concept of Eutrophication,when bodies of water become choked with algae and decomposers after excess nutrients end up in them. Here is a photo from the TakePart.com website.
