When I got to the lab today. I noticed my aquarium not having half of its water. This was much more than usual. I'm assuming that either someone knocked it over or the heat lamps were turned up a bit evaporating more water. The only organism that showed to have and increase instead of a decrease were the Rotefers. They were much more abundant than they were in previous weeks. The only organisms still present in any significant number were the Vorticella, the Amoebas, and the seed shrimp, though the Vorticella have become less colonized and in fewer number. The plants are becoming more of a yellow color due to the lack of chlorophyll consumed by the different micro organisms. The units were undoubtedly consumed by the microbes, as the organisms have been seen eating the plants and also having parts of the plant in them, as well as a by their increase in number. As a result, the plants appearance under a microscope are becoming much more clear and naked.
