What is a chemical produced by a microorganism that is toxic to other microorganisms?

Agitation System
Algaecide (Algicide)
Antibiotic
Algae

The correct answer is: Antibiotic

Antibiotics, such as penicillin, are chemicals that are produced by microorganisms, such as fungi, and are able to inhibit or kill other microorganisms. This is why they are often used as medicine to fight bacterial infections. Agitation system (A) is a mechanical process used in industry to mix fluids, and is not produced by microorganisms. Algaecide (Algicide) (B) is a chemical used to kill algae in bodies of water, but it is not produced by microorganisms. Algae (D) are a diverse group of photosynthetic microorganisms, but they are not always toxic to other microorganisms. So, the most accurate answer is C Antibiotic.
