Observation 5

This week the amount of water in the aquarium has been drastically reduced. Nothing has been spilled. I noticed that everyone else’s water levels were also reduced in volume. The plants seemed to be thriving. There was an increase in the mass of plant material. There was moss growing in the aquarium. Its rhizoids were visible. There also seemed to be a significant decrease in the number of organisms living in the aquarium. The only types of organisms that were observed were multiple Rotifers and two Turbellaria. Neither the Rotifers were feeding where as the Turbellaria were not. The food pellet had been either dissolved or completely consumed.

Observation 4

There were many more rotifers and other organisms than was previously observed. It seems as if the organisms have been eating away at the food pellet that was inserted the pervious week. It was also observed that there were multiple diatoms which were living in the Micro-Aquarium (Rainis, 1918).
