Bacteria help you digest food.
A
True
B
False
Explanation: 

Detailed explanation-1: -Bacteroidetes and Firmicutes are the main bacteria in the metabolism of undigested food remnants. They help to digest dietary fiber and polyphenols by a complex metabolic energy-harvesting mechanism, which is based on cross-feeding and co-metabolism.

Detailed explanation-2: -The three or so pounds of bacteria living in our gut-mostly in the large intestine-help us digest all manner of food.

Detailed explanation-3: -Short Chain Fatty Acids (SCFAs) Bacteria in the colon are able to break down complex carbohydrates using enzymes such as polysaccharide lyases to a fermentable form, resulting in the production of large amounts of SCFAs.

Detailed explanation-4: –E. coli Help in the digestion of food by using up nutrients that some bacteria need to live. These bacteria also take up space in our gut, making it impossible for harmful bacteria to establish themselves and grow.

Detailed explanation-5: -We wouldn’t be able to digest our food properly without our gut bacteria. Crops around the world would start to die without the nutrients generated by microbes.
