Which Key Concept is best supported by the evidence in the image?

• Antibiotics reduce the number of helpful and harmful bacteria in the microbiome

• The human body provides an environment (food and space) for bacteria to survive

• An infection of harmful bacteria in the human microbiome can make a person sick

• Living things with fewer than normal helpful bacteria in their guts can become infected more easily because there is more food and space available for harmful bacteria
