Observation 4

During this week's observation, I noticed that there was not much change in the overall setting of my Micro Aquarium. I am still seeing the same organisms doing the same things. The amount of activity has neither increased nor decreased.

Organisms that are still present in my Micro Aquarium include: euglenoids, vortacella, green algae, rotifers, paramecium, actinosphaerium, and a handful of creatures that I am still not sure as to what they are. I have yet to see the cyclops from my initial viewing of my Micro Aquarium. I believe it has died and something ate it.



Most of the activity in the Micro Aquarium seems to be near Plant B. One hypothesis I have is that this plant contains more desirable nutrients than Plant A. Many of the organisms I have found in the Mirco Aquarium seem to eat Plant B or feed off of it. Another hypothesis I have is that Plant A is not a familiar plant to the organisms living in my Micro Aquarium. It could be that Plant A is not a native species to the natural ecosystem of the organisms found at my water source (source 11).
