<h3>What is bacteria?</h3>

The majority of bacteria are free-living, omnipresent organisms that frequently just have one biological cell. They make up a sizable group of prokaryotic microorganisms. Bacteria, which are among the earliest life forms to exist on Earth and are typically a few micrometers in length, are found in most of its environments. The deep biosphere of the Earth's crust, acidic hot springs, radioactive waste, and soil all support bacterial life. By recycling nutrients, such as fixing nitrogen from the atmosphere, bacteria play an important role in many stages of the nutrition cycle.
