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)

Answer 1

The relationship between gut bacteria and humans is symbiotic; the bacteria benefit from the nutrients we provide, while they help maintain our health by outcompeting harmful organisms. If we take too many bacteria-killing antibiotics without medical guidance, it can disrupt this balance, potentially leading to overgrowth of harmful bacteria, reduced nutrient absorption, and conditions like antibiotic-associated diarrhea or Clostridium difficile infections.
