Observation 3

In my micro aquarium this week i noticed that there wasn't as many organisms in my tank.  During the second week a food pellet was added so they thrived off that.  But this week they had to go back to their normal eating habits which killed some of the tank.  Two organisms stood out to me this week.



The Vorticella sp.(Patterson 1996)  This was a moving organism that's flagella was attached part of the plant Amblestegium varium (Hedwig) Lindberg. Moss.Collection from: Natural spring. at Carters Mill Park, Carter Mill Road, Knox Co. TN. Partial shade exposure. N36 01.168 W83 42.832. 10/12/2014.  
The top part of the plant, that looks like a triangle, looked to have blades spinning out of its opening.  It was also swaying in a back and forth motion.  I think that it was multi cellular and chlorophyll green organism.  I found it near the middle layer of the tank.




The second one i observed was the Monostyla sp. (Pennak, 1953) it is a rotifer.  This was a moving organism that has a flagella.  It is a multi cellular organism and is non-chlorophyl green.  I saw many rotifers on all levels of the tank.
