Explanation:
Antibiotics are chemicals that kill or inhibit the growth of bacteria and are used to treat bacterial infections.
They are produced in nature by soil bacteria and fungi. This gives the microbe an advantage when competing for food and water and other limited resources in a particular habitat, as the antibiotic kills off their competition.
Each type of antibiotic only works against certain types of bacteria or parasites. This is why different antibiotics are used to treat different types of infection. The main types of antibiotics include: Penicillins - for example, phenoxymethylpenicillin, flucloxacillin and amoxicillin.May 27, 2020
