Day 5 July 16


We didn't get a chance to check our ecosystem on Thursday or Friday, which means that it has been on its own for four days. Today, we should be able to notice if anything is negatively affecting it. I was concerned about the amount of algae present in the water when we started it.
It is now 9:00 in the morning. We have observed that the condensation in the container is not blocking our view of the ecosystem anymore. There is condensation in each layer, but not as much. The water has cleared up in the aquatic ecosystem. The fish are very active and there is not as much algae present. The plant material in the ecosystem is helping clean the water. The decomposition layer now has mold growing on the banana peel. There is a fair amount of condensation in this layer. I think the condensation is occurring during the decomposition process, but I am not sure. A few of the plants are dying in the terrestrial layer. I don't think we buried the roots into the soil deep enough.
