Week 3

The micro aquarium was business as usual.  It has been just a little over two weeks since the beta food was added.  There maybe a slight drop in the quantity of organisms the past weeks.  I noticed that the two plants that were inserted during the initial setup are beginning to visually shrivel and turn brown.  This could be attributed to being under the lights in the lab constantly or from microorganisms doing harm to the vascular cambium or doing something to inhibit uptake of water by the plants.  It could also simply be from a lack of necessary nutrients to stay alive.  I wanted to get some pictures this week but I was running late for a class project meeting in so I only had time for a quick stop in the lab for observations.  Only one more week before the micro aquariums are shut down!
