The following points highlight the seven modes of nutrition in protists. The modes are: 1. Photosynthetic 2. Holozoic or Zoo-Trophic 3. Saprobic or Saprotrophic 4. Parasitic 5. Mixotrophic 6. Symbiotic 7. Pinocytosis. Modes of Nutrition # 1. Photosynthetic (Holophytic): In this mode, the organisms prepare their food from CO2 and water by utilizing sunlight with the help of photosynthetic pigments [...]
