The relationship between gut bacteria and humans is a mutualistic one, where beneficial bacteria thrive on the nutrients we provide while helping to maintain our health by outcompeting harmful pathogens. If we take too many bacteria-killing antibiotics without medical guidance, we risk disrupting this balance, potentially leading to an overgrowth of harmful bacteria, antibiotic resistance, and various gastrointestinal issues, such as diarrhea or infections like Clostridium difficile.
There are good bacteria that live in our gut. They benefit from us because they feed on what we eat, and we benefit from them because they keep harmful bacteria away. In one or two sentences, define this relationship and describe what could happen if we took too many bacteria-killing antibiotics without the advice of a physician.(2 points)
