What substance are the bacteria (microorganisms) breaking down in the digestive system of cattle? Describe the digestion of this substance.

The Bacteria or microorganisms are present in the rumen of cattle that aid in the digestion of cellulose and grains in the digestive system of cattle.

The process of digestion of cellulose by bacteria in cattle is anaerobic digestion and includes two steps – the production of the required enzymes and the fermentation.

In the fisrt step of production of enzyme, the microbes or bacteria are found in the first chamber of the stomach. These bacterias or microbes releases several enzymes that helps in splitting the cellulose into smaller carbs such as glucose.

These smaller carbs are the move to thrd chamber of the stomach and fermented. the required nutrients are absorbed. The digested food then finally reached at fourth chamber (acidic part), where the remained food is digested and passes to the small and large intestines.
