Question

how the digestion in micro-organisms works​

Answer 1

Explanation:

Your large intestine is not just made up of cells. It is also an ecosystem, home to trillions of bacteria known as the "gut flora" (Figure below). But don't worry, most of these bacteria are helpful. Friendly bacteria live mostly in the large intestine and part of the small intestine. The acidic environment of the stomach does not allow bacterial growth.

Gut bacteria have several roles in the body. For example, intestinal bacteria:

• Produce vitamin B12 and vitamin K.

• Control the growth of harmful bacteria.

• Break down poisons in the large intestine.

• Break down some substances in food that cannot be digested, such as fiber and some starches and sugars.

• Bacteria produce enzymes that digest carbohydrates in plant cell walls.

• Most of the nutritional value of plant material would be wasted without these bacteria.
