Bacteria obtain energy through various metabolic processes, primarily by breaking down organic or inorganic substances. Many bacteria are heterotrophic, meaning they consume organic compounds for energy, while others are autotrophic and can produce their own energy through photosynthesis or chemosynthesis. In anaerobic conditions, some bacteria can derive energy from fermentation, while others utilize respiration, either aerobic or anaerobic, to generate ATP. This energy is then used for growth, reproduction, and other cellular functions.
