Why is bacteria found everywhere?
First of all, since bacteria is the plural of bacterium, you should ask why
*are *bacteria found everywhere. Through evolution, bacteria have evolved to
adapt to survive in any environment where there is organic (meaning alive or
once living) material. Some bacteria have even evolved to live in
environments where there is only inorganic material like Iron or Sulfur or
ammonia. In short, bacteria live everywhere because they can.
