Explanation:

Bacteria in the human body play crucial roles such as aiding digestion (helping break down complex foods like fiber), supporting the immune - system (training immune cells to recognize pathogens), and producing vitamins (like vitamin K and some B - vitamins). Without bacteria, digestion would be severely impaired, the immune system could become less effective and more prone to over - reactions, and there could be vitamin deficiencies.

Answer:

If a human lost all their bacteria, digestion would be disrupted as bacteria help break down certain foods. The immune system would likely be weakened and more prone to abnormal responses, and there could be vitamin deficiencies since some bacteria produce essential vitamins.
