autotrophic bacteria

Autotrophic bacteria are microorganisms that produce their own food by converting inorganic substances, like carbon dioxide, into organic compounds through processes such as photosynthesis or chemosynthesis. Unlike animals, they don’t need to eat other organisms; instead, they use energy from sunlight or chemical reactions. These bacteria play a vital role in ecosystems by forming the base of food chains and recycling nutrients. Examples include cyanobacteria, which perform photosynthesis, and certain bacteria that obtain energy from chemicals in their environment. They are essential for maintaining balance in many natural habitats and supporting life’s overall sustainability.
