Final answer:
The suffix for antimicrobials that kill microorganisms is '-cidal', while those that inhibit growth use '-static'. Examples include bactericides and bacteriostatic treatments.
Step-by-step explanation:
The suffix used for antimicrobials that kill microorganisms is -cidal. For instance, substances that kill bacteria are called bactericides; those that kill viruses are called viricides; and those that kill fungi are named fungicides. On the other hand, agents that do not kill but instead halt the growth of microbes are identified by the suffix -static, with examples including bacteriostatic and fungistatic treatments. The use of -cidal or -static interventions depends on the types of microorganisms targeted, the concentration of the chemical, and other factors related to treatment application.
