Day 28

          The first thing I noticed today was the food pellet that was placed in everyones micro-aquarium is not gone.  Every time I looked at my aquarium under the microscope there was always a huge abundance of organisms surrounding the food pellet, most of them feeding off of it.  In only two to three weeks these tiny organisms have demolished the pellet.  I find this amazing.  This being the last week of observations I really wanted to focus on how organisms have changed, multiplied, or the variety of new organisms that have appeared.  Compared to the first week the number of organisms have increased dramatically, along with the size of these organisms.  The first week or two I only saw a select few rotifers, but now they are in the plants, the soil, and swimming around in the space with nothing.  Along with the rotifers, the seed shrimp have increased in numbers and size, the first week I spotted one seed shrimp, this week I found five. Today I noticed a bunch of "Philodina rotifers" (Micro Invertebrates) that some how I have not stumbled upon in the past.  These rotifers seem to stay in one place and they have multiple cilia on the opposite side of the end that is attached to something.  Other then that everything I saw today is something that I have photographed already or have described in my other blogs.
