    Bacteria do not necessarily need a host to survive. While some bacteria are indeed pathogenic and rely on a host organism to provide them with the necessary nutrients and environment to grow and reproduce, many bacteria are capable of surviving in various environments independently. These bacteria are referred to as free-living bacteria. They can be found in soil, water, air, and even on surfaces. Free-living bacteria obtain their nutrients from organic matter present in their surroundings and can carry out metabolic processes necessary for their survival without depending on a host organism. Examples of free-living bacteria include those involved in the decomposition of organic matter and those found in natural ecosystems such as oceans and forests.
