Botany 111 Term Project Ehughes7: Final Observation

The final observation showed the boom in the Coleochaete sp. population, which is a green algae that was present everywhere, but an apparent diminishing of the living organisms that were present. I did noticed the presence of several more Rotifers than I had before. There was a large increase in the amount of nematodes present, in which they were not hiding in the soil as they did previously, possibly because the apparent degradation of it. There was a lot of stringy Algae present also, which looked like the whole micro aquarium was covered in hair. In addition to this, I notice the presence of many expended diatoms and dead organisms ominously littering many parts of the tank. The water level had also dropped since the earlier observation, which could have been some of the result of the organisms numbers diminishing, or their numbers might have diminished due to an expiring of the beta food tablet that was administered. Below I have provided some images of some of the organisms and species that I had observed over the course of the micro tank study.
