Question

What is the primary source of antibiotics?

• A. Chemical synthesis
• B. Plants
• C. Microbes
• D. All of the above

Answer 1

The correct option is C Microbes

Antibiotics are usually produced by microbes themselves. When two microbes are fighting for resources in a small area, one of them could produce an antibiotic that might kill the other and capture the resources for itself. Although initially antibiotics were isolated from microbes, today pharma companies synthesize their own antibiotics through artificial methods as well.
