Nutritional Types of Bacteria - Classification and Metabolic Modes
Summary :Classification of bacteria based on nutritional requirements and energy sources including autotrophs (CO₂ only carbon source, chemolithotrophic/photosynthetic energy), heterotrophs (organic carbon), lithotrophs (inorganic chemical energy), phototrophs (light energy), with examples of each type. Covers metabolic strategies, growth requirements, and ecological roles in nutrient cycling.
