Answer» Heterotrophic organisms obtain energy through the INGESTION of energy-rich food. Theingested food should be digested into small compounds to absorb as nutrients. Intracellular and EXTRACELLULAR digestion are the TWO methods of digestion of food in the above-mentioned organisms. Intracellular digestion mainly occurs inunicellular organismssuch asprotozoans. In ADDITION, extracellular digestion occurs in animals with a digestive system and infungi. Themain differencebetween intracellular and extracellular digestion is thatintracellular digestion occurs inside the foodvacuoles WITHIN the cell whereas extracellular digestionoccurs outside the cell in the lumen of the alimentary canal or on the decaying organic materials. |
