Which of the following describes an organism that is likely to be harmful to human health?

The choice that correctly describes an organism likely to be harmful to human health is germs. Germs broadly refer to pathogenic microorganisms, which include bacteria, viruses, fungi, and protozoa that can cause disease in humans. When referring to germs, the focus is on those microorganisms that have the potential to disrupt normal bodily functions, leading to various health issues.

In contrast, beneficial bacteria play essential roles in processes such as digestion and maintaining a balanced microbiome, while non-pathogenic microorganisms are generally harmless or even helpful to humans. Symbiotic organisms may live in close association with humans or other species, often providing benefits without causing harm. Understanding the differences among these groups highlights the significance of recognizing which organisms may pose risks to health.
