MicroAquarium Observation 10.22.09

There were rapidly moving tiny green organisms swarming in the purple-blue pods, which were identified by Dr. McFarland as the plant bladders (pictured). With the more powerful microscopes used in this lab, I was able to spot tiny organisms hiding underneath the leaves coming from the stems of plant A. These organisms resembled bubbles and several would appear to be bunched together under a single leaf, possibly feeding off of the nutrients coming from this area of plant A. After spotting these new, different species in my second observation, I wondered how the larger moving organisms interacted with these tiny bubble-like organisms. I then noticed an organism larger than the ones noted in the first post, and what appeared to be the smaller, originally noted organism inside of it while this larger creature was experiencing a sort of full-stomached siesta. Are some moving organisms feeding on the others?

I then noticed another new detail of my MicroAquarium, transparent yellow sacks, unmoving, laying close to the dirt at the bottom. These sacks had tube-like parts in its interior. Upon closer and lengthy observation, I noticed curious behavior of some of these interior parts. There was something in the shape of an acorn attached to a string that floated stationary for a few seconds, then appeared to whip around the inside of the sack, and then return to its stationary state. There was another immobile part inside of this sack that had a high number of hairy spikes protruding from the bottom of it.
