One of the main ways bacteria help humans is by living in their digestive system. Bacteria actually digest some of the food we eat and pass along the nutrients to us. There are also bacteria that are useful to us by helping the plants we eat grow better. They allow certain plants like peas and beans to use nitrogen from the air as fertilizer. Other bacteria help to decompose rotting matter so that we don't get sick from that - and it also fertilizes more plants that way.
