Answer 1

An antibiotic is any substance produced by a organism that is antagonistic to the growth of prokaryotes.

Step-by-step explanation:

Antibiotics can be defined as natural compounds - when produced by fungi or bacteria - or synthetic compounds capable of interfering with bacterial growth or causing the death of these beings. In either case, antibiotics can be defined as any substance produced by an organism that is antagonistic to prokaryote growth. When they cause bacteria to die, they are called bactericides, but when they only inhibit their growth, they are called bacteriostats.
