Which term describes organisms that are considered not harmful and may even be beneficial?

The term that describes organisms considered not harmful and that may even provide benefits is nonpathogenic. Nonpathogenic organisms are those that do not cause disease or harm to their host. In fact, many nonpathogenic organisms, such as certain bacteria found in the human gut, play crucial roles in digestion, nutrient absorption, and maintaining overall health by outcompeting pathogenic bacteria.

Pathogenic organisms, on the other hand, are those that can cause disease and harm. Parasitic organisms depend on a host for survival and often cause damage to the host. Mutagenic refers to substances or factors that can cause changes in the DNA of organisms, potentially leading to mutations and diseases. Understanding the role of nonpathogenic organisms is essential in the field of sanitation and disinfection, as they contribute to a balanced ecosystem and can aid in various processes, including biodegradation and nutrient cycling.
