If scientist added a chemical to destroy the arctic microbes, what positive and negative consequences could result? What population settings could you adjust in the simulation to test components of this solution?

It destroy both harmful and beneficial microbes.

Explanation:

If scientist added a chemical to destroy the arctic microbes, the beneficial as well as harmful microbes also eliminated from that area where chemical is applied. The removal of harmful microbes is a good thing but the removal of beneficial microbes brings instability in the environment. These beneficial microbes helps in the recycling of nutrients for the plants present there. So the negative effect of chemical is that it also effect the beneficial microbes which are necessary for the ecosystem.
