Question 1

Why are microbes found in specific areas?

Answer 1

Due to different environments.

Some bacteria like dry, others like wet. H. pylori can survive in the stomach at a pH of 1-2, where no other bacteria can survive. Some bacteria have adaptions such as Enterococcus’s ability to destroy bile (which normally destroys other bacteria).
