Answer:
water
Explanation:
Water puts out fire by creating a barrier between the fuel source and the oxygen source (it also has a cooling effect which has to do with the energy required to convert liquid water into water vapor). It does this because it is a completely, 100% oxidized material. It simply cannot oxidize any further so it will not “burn”. This smothers the fire. The same thing would happen if you used the ashes that remained after a completely spent fire. Or, as I mentioned before, CO2.
Answer: In all of these carrying capacity would go down substantially.
Explanation: This is because these natural disasters are very detrimental to the environments and would decrease life.

Answer:
All results for the experimental groups involving wing surgery would be invalid.
Explanation:
The experimental group involving wing surgery would not lead to correct results because it is a direct parameter that is impaired. This has been already clearly stated in the question that these flies are prone to attack compared to those which are not treated. There could be several reasons for that such as: (1) the reattachment would not have been successful, and/or (2) the flies' health (fitness) status would have been compromised.
On the other hand, it is not correct that all experimental groups will lead to incorrect results because the untreated flies were not attacked (or less attacked). Similarly, there is no condition given for houseflies rather only zonosemata flies. So 3rd option is also not possible. Finally, the reliability of the results would definitely change because the treated flies would be more attacked and lead to a clear difference in results.
