Change in the Biotic components
When we first put together our eco column, we planted some bean seeds and weeds, these have now grown about five centimeters over the past couple of weeks.












Here are the beans and weeds currently. and the second image shows the beans and weeds after we just planted them.

Animals

There is a large number of fruit flies that are inside our decomposition zone. they must be feeding off the decomposing food and fruit. W put in a couple of fruit flies when we made the eco column and so they must have laid some eggs resulting in many more flies in total.

Here is a photo of our decomposition zone. you cannot see any flies inside there as they are very small and are hard to see through the plastic bottles.
