Microbes - Any minute, simple, single-celled form of life, especially one that causes disease.

What are microbes?

Microbes are present in almost every environment, in the soil, the air, even animals and plants.

They are found all over our bodies, on our skin, in our mouth and in our stomach.

Most are harmless, even beneficial. Microbes that live in our stomach help us to

digest our food.

Where do microbes live in our bodies?

They help create medicine to fight off sickness.

They are also helpful in the bodies function of protecting the body from bacterial diseases.

Question: If this is true and microorganisms can be used to produce certain farm crops at this rate, why are there places in the world where people are still dying of starvation?

With a generation time of twenty minutes, and with no limiting factors, a single bacterium, with a biomass of only l0-12g, would produce 22 x 1025

tons of biomass - 4000 times the mass of our planet - within two days. In other terms, a bacterium could, in a non-restricting environment, produce 1011 times its own biomass of protein alone in a single day.
