Also like plants, they give off oxygen. Other bacteria absorb food from the material they live on or in. Some of these bacteria can live off unusual foods such as iron or sulfur. The microbes that live in your gut absorb nutrients from the digested food you've eaten.
Anaerobic bacteria are germs that can survive and grow where there is no oxygen. For example, it can thrive in human tissue that is injured and does not have oxygen-rich blood flowing to it. Infections like tetanus and gangrene are caused by anaerobic bacteria. Anaerobic infections typically cause abscesses (buildups of pus), and death of tissue. Many anaerobic bacteria produce enzymes that destroy tissue and, sometimes, potent toxins. Besides bacteria, some protozoans and worms are also anaerobic.
