Symbiotic bacteria

Symbiotic bacteria are microscopic organisms that live in close and mutually beneficial relationships with their hosts, which can be animals, plants, or humans. These bacteria help their hosts in various ways, such as aiding digestion, protecting against harmful pathogens, and producing essential nutrients. For example, in humans, gut bacteria break down food and synthesize vitamins. In return, the host provides the bacteria with a stable environment and nutrients. This partnership highlights the important role of bacteria in maintaining health and balance within ecosystems.
