Week 10

The string is now completely disintegrated. This most likely means that the top of the ecosystem will began dying due to the lack of access to the water source. The plants at the top do look very healthy though. The sprouts are 8 cm and 5.5 cm. Half of the top bottle has condensation on it. The tallest plant has 3 healthy leaves and one dead leaf. There is mold on the soil, and the soil is starting to pull away from the sides of the bottle. It has already started drying out. In the bottom of the ecosystem, lots of snails have appeared. Maybe the snails reproduced? However, the 2 main large snails that we have been observing appear to be dead. We have counted 7 baby snails in total. 1 of the big snails is possibly dead. It has stayed in the same position for the past 2 weeks, submerged within the rocks. Half of the elodea appears very healthy, while the other half is brownish and translucent. The roots growing off of the elodea is still touching the bottom rocks. There is condensation on the top of the bottom bottle as well. The elodea is probably that healthiest part of the ecosystem altogether. I would not like our group to volunteer to poke a hole in the bottle. I would like our system to stay closed in order to observe what might happen to the plants and soil.
