Conclusion- Our ecosystem failed. And it smelled like dead, rotting onions. During our autopsy we discovered that our onions had rotted from the inside out, and we did not find any of the three worms we put inside. The leaves were soggy, and slightly moldy. The corn was gone. There was also, at one point, a weed growing inside that had been brought in through the soil. It was gone as well.

Reasoning- My theory as to why our ecosystem failed is that it ran out of Carbon Dioxide. Elijah exhaled into it before we sealed it, to prolong the supply, but apparently that wasn't enough. Our ratio of oxygen producers to carbon dioxide producers was not balanced correctly.

What would I do differently?- I think, if anything, I would only put in two onions. I would try to find more worms to put inside too. I believe our ecosystem would have been more successful if there were more organisms producing carbon dioxide.
