Which term describes organisms that cause disease?

The term that describes organisms that cause disease is "pathogenic." This term specifically refers to microorganisms, such as bacteria, viruses, fungi, or parasites that have the capability of causing harm or disease to a host. Understanding the role of pathogens is crucial in odor control situations, especially when dealing with contaminated environments, since certain odors can result from the activity of these harmful organisms.

While fungi and bacteria can be examples of pathogenic organisms, not all fungi and bacteria are disease-causing. Therefore, they do not encompass the entire concept of pathogens, which includes a wider range of organisms. Nutrients, on the other hand, refer to substances that provide nourishment and are not directly related to the concept of disease causation. In summary, "pathogenic" is the most accurate term to describe organisms specifically associated with causing disease.
