- from Bacteria
You probably don’t think of yourself as a habitat.
But to bacteria you are. Scientists call the community of bacteria and other micro-organisms that live in a person a microbiome.
You, as a microbiome, are home to trillions of cells of bacteria and other microorganisms. In fact, the number of microorganism cells in your body outnumber your own human cells 10 to 1! If you weigh one hundred pounds, you could be carrying around three pounds or more of bacteria. They live all over: in your gut, on your skin, in your mouth.
