Today we looked at our closed ecosystem and we were able to noticed that some of the living organisms were still alive. We noticed the 3 snails that we began with are still alive - two of them were on the top (along the bottle, and the smallest one was at the bottom of the bottle). We also noticed that there was a lot of condensation, in the bottom half (aquatic part) and the top half (terrestrial part). One of the most exciting things that we were able to see was the seeds sprouting. Since we used different types of seeds, we also noticed that too. It seems like the corn, green beans, and spinach started to grow (not too sure that the broccoli did). One of those plants is growing up the bottle wall.
Some of the organisms that we did not see were the daphnia, there were 7 at the beginning and we were only able to notice 1. Also one shrimp was more visible than the others because it was swimming around.
The water level was still the same since the beginning, the was not a dramatic change on that. Water looks clear and it seems that there is no water dripping down the aquatic portion, as it was doing the first day. The elodea seems healthy and greener, providing our ecosystem with oxygen, for our living organisms to remain alive.
