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) really

The relationship between gut bacteria and humans is mutualistic, as beneficial bacteria help with digestion and protect against harmful pathogens while we provide them with nutrients. Taking too many antibiotics without a physician's guidance can disrupt this balance, potentially leading to harmful bacterial overgrowth, antibiotic resistance, and a weakened immune system.
