text: You may leave it as it is in the initial state, however you may wish to note the varied amounts of water. I would suggest that instead of direct water by volume, you try running your hypothesis on the basis of moisture exposure, in conjunction with sunlight, accelerating the decomposition process. More directly, the rate in which decomposition is accelerated by the introduction of both variables. Due to the introduction if varying forms and rates of decomposition, you may wish to include the parasites that become present during the breakdown stages.\n    Also, while your hypothesis is that an orange will decompose BEST in a condition combining both sunlight and water, you must allow for atmospheric conditions such as air, and temperature. But the AMOUNT of water / moisture will have a direct effect on your results.\n                  Good luck!!
