What is difference between intracellular and extracellular digestion?
Intracellular digestion takes place in unicellular organisms such as protozoans while extracellular digestion occurs in animals and fungi. In extracellular digestion, the breakdown of food materials into small molecules occurs outside the cell in the lumen of the alimentary canal or on the decaying organic materials.
Are Saprobionts bacteria?
Saprobionts such as bacteria (and fungi) act as decomposers. They carry out extracellular digestion of plant and animal wastes, using some of the organic compounds as respiratory substrates to power their own biological processes. Organic compounds are thus converted into carbon dioxide and water.

Unlike the small intestine, the large intestine produces no digestive enzymes. Chemical digestion is completed in the small intestine before the chyme reaches the large intestine. Functions of the large intestine include the absorption of water and electrolytes and the elimination of feces.
How long does food stay in large intestine?
After you eat, it takes about six to eight hours for food to pass through your stomach and small intestine. Food then enters your large intestine (colon) for further digestion, absorption of water and, finally, elimination of undigested food. It takes about 36 hours for food to move through the entire colon.
