Algae Pond

PNNL-Pacific Northwest National Laboratory. (2011, April 11). Algae pond [Image]. Flickr. Retrieved July 19, 2011, from http://www.flickr.com/photos/pnnl/5611334365/ The image is a credible source since it was recently taken by a scientific organization. This shows an algae open pond system and will be useful to provide visuals in my paper.
