Changes in the biotic components

Our eco-column has sustained itself for 1 week now! Here are some observations of the biotic components:

2013/02/21

• We added a spider in the terra zone last week and that spider has now died. We also added about 30 ants, and at the moment it looks like they are all still alive.
• We found a small worm-like creature in our aqua zone. We will be adding a short video of the worm moving, that was taken under a light microscope.
• The grandilla outer shell is slowly decomposing in our decomp zone.
• The snail has started eating the tomato plants

2013/02/28

• A plant has begun to grow from our decomposing piece of tomato (you can find more info on this here: http://leavingbio.net/plant%20responses.htm)
• The growth of the plants in the Terra zone was great, the weed has grown approximately 2,5cm in height. There is nine leaves on the succulent plant.
• Most of the ants has died as we can only see a few.
• The water plants in the aqua zone has grown roots die to a lack of oxygen.
• The tomato has almost completely decomposed.

2013/03/04

• The ants were stuck tot the side of the terra zone because of the water vapour in the eco-column
• The snail oin the terra zone has started to eat the tomato plant
