Conclusion-biotic factors

The 2 biotic factors in the bottom level, the aquarium, were 2 aquatic plants and a goldfish. As the experiment was conducted it was obvious that the health of the fish and plants were declining. Based on the observations made of the browning and falling of of the plants' leaves and steams, also yellowing water and declining water quality based on Ammonium Nitrate and turbidity testing. This was confirmed when the fish itself died and the plants fully fell apart. Although another theory is that maybe the fish's death was caused by starvation, not getting feed for 4-5 days can do that to a fish. then the increased bacteria level due to the decaying fish could have caused further plant death and worsening water quality. The decomposition chamber however seemed to have flourished. With an immense increase in Fruit flies the small spider we put in the chamber, Mr.Chuckles, seemed to grow bigger, flourishing, and on the last day it looked like it had even layed a sack of eggs on the side of the chamber, although it had to be destroyed when the chamber was cleaned out. On the top level the grass itself did well. It was not super thick and abundant but it got very tall and grew very fast, when watered. At the end though, when we hadn't watered it for several days, the soil became dry and the grass appeared droopy. So overall it seems in order of worst to best the health of the Eco-column's biotic factors saw the aquarium chamber as the worst off, with the grass next, and the decomposition chamber as doing the best.
