Final Observations Week 5

Observations on Thursday November the 14th 2013. The last week of observations were done at the bottom, middle, and top of the micro aquarium. Many of the micro organisms seen throughout the blog are still surviving. Some of the diatoms though have died, their silica cell walls are no longer  intact. In lieu of their death a service was held by some of their good friends the amoebas. At the bottom of the micro aquarium a new micro organisms were identified. One of them can be seen in figure 1 the Tachysoma sp. identified by Free-Living Freshwater Protozoa by D. J. Patterson. Another one the Pediastruim sp. in figure 2 was seen in the middle of the micro aquarium and was identified by Handbook of Algae by Herman Silva Forest. With in the micro aquarium a abundance of life can be seen with a microscope, in total over eleven micro organisms where identified, but many more where observed.
