The following points highlight the five main types of autotrophic and heterotrophic nutrition in bacteria. The types are: 1. Photoautotrophic Bacteria 2. Chemoautotrophic Bacteria 3. Saprophytic Bacteria 4. Symbiotic Bacteria 5. Parasitic Bacteria. Type # 1. Photoautotrophic Bacteria: The bacteria possess photosynthetic pigments of two types, bacteriochlorophyll and bacteriophaeophytin (chlorobium chlorophyll).
