Observation of Changes in the biotic components

Today - 12 March. It seems that our plants are shrinking and some of the leaves are going. We reaserched this and found it can be caused by a few things. Over fertilising, high heat, high light, over watering and under watering. We believe the cause of our leaves vurling and darkening to a blackish/brownish ishigh heat and too much moisture in the terra zone as there was initially a lot of water when we started the eco system.
 
The tips of the plants are also rough and look like they have been eaten off by the large insect.
 
 
There are no fruit flies left in the decomp zone. We believe that they have escaped through the air holes in the side of the plastic bottle. We made the holes for air transfer in and out of the decomp zone. We never expected any fruit flies to fly into this zone.
 
 


4 March - 11am
The fruit flies have all disappeared out of our decomp zone.
The praying mantis and other large unidentified insect are still alive.
The plants are all looking green although the one plant had a few darker blackish leaves.



1 March - 9:30am


Fruit flies have flown into or have developed in our decomp zone.
The pray-mantis is still alive in our Eco-column.
The plants are all green.






25 February - 3:30pm

An alive insect was seen today when we observed our ecosystem. This shows the ecosystem is self sustaining as the insect requires and is getting oxygen from the living plants!




Today we found some white fungi in the decomp zone! This will be very interesting to look at under a microscope!
