Bacteria break down (or decompose) dead organisms, animal waste, and plant litter to obtain nutrients. But microbes don't just eat nature's waste, they recycle it. The process of decomposition releases chemicals (such as carbon, nitrogen, and phosphorus) that can be used to build new plants and animals. That is, chemicals that used to be a flower or a vegetable will eventually become part of another living thing.
The immune system. White blood cells. The body has an immune system that kills microbes if they get past the natural barriers. White blood cells are very important in the immune system. There are different sorts of these cells, but they can do two main jobs. Some white blood cells can engulf microbes and kill them. Some white blood cells can make substances called antibodies that stick to microbes. Microbes have chemicals called antigens.
