Week 4

Thursday, November 12, 2007
When I first looked at the microaqarium, I noticed a lot of dead matter that has collected at the bottom of the aqarium. The algae has continued to grow; however, now it has spread to the entire aquarium instead of just in the corner it had been place in originally. Once I began to look at my aquarium under the microscope, I could see different kinds of algea growing all over the sides of the aquarium. The algae increase in numbers; however, most of the organism decreased. The only dead organisms I could distinctly see in the material at the bottom of the aquarium was several freshwater shrimp. The only living organisms I saw in my aquarium was rotifers and annelids. The vorticella also remained about the same in numbers. In fact, I also witnessed the vorticella budding. I did not see any new organism this week.
