Week 5: Despite the increased action and vast number of organisms observed last week, the number of organisms seen this week is dwindling. This may be due to the fact that the micro-aquarium seems to have lost a larger amount of water this week than in prior weeks. Few Crustacea-Ostracods are once  present moving on top of the leaves, and cyanobacteria colonies are there but less than previously present. The zooflagellates that appeared dead and decomposing are still present but are even less noticeable this week. Leafs of the coniferous plant now barely have any organisms swimming in and out of it. There is now an even larger buildup of dead organisms and plant material at the bottom of the micro-aquarium than last week. Vorticila were observed this week for the first time and were surprisingly non-mobile.

Week 4: Now that the new plants and water sources have began to adjust and integrate with the rest in the micro aquarium, even more interaction is occuring within the micro aquarium . Crustacea-Ostracods are once again present moving on top of the leaves. There are now even more cyanobacteria colonies than previously present. The zooflagellates that appeared dead and decomposing are still present but are less noticeable. Leafs of the coniferous plant still have organisms swimming in and out of it. There is also a larger buildup of dead organisms and plant material are the bottom of the micro-aquarium.

Week 3: With the addition of some new plants and water sources as seen in last week's blog, organisms started to reappear within the micro-aquarium. Crustacea-Ostracods are once again present moving on top of the leaves. There are now more cyanobacteria colonies than previously present. What look to be zooflagellates appear dead and decomposing. Leafs of the coniferous plant have organisms swimming in and out of it. There is also a larger buildup of dead organisms and plant material are the bottom of the micro-aquarium.
