What is the difference between non-pathogenic and pathogenic microorganisms?

Answer 1

Non-pathogenic microorganisms are those that do not cause disease or harm to humans or other organisms. They can exist in the environment or in the human body without causing any negative effects. These microorganisms may have beneficial roles, such as aiding in digestion or providing nutrients.

On the other hand, pathogenic microorganisms are capable of causing diseases. They can invade and multiply within a host organism, causing harm and leading to the development of various diseases and infections. Pathogenic microorganisms can cause a wide range of illnesses, from minor infections to severe and deadly diseases.

Overall, the key difference between non-pathogenic and pathogenic microorganisms lies in their ability to cause harm and disease in living organisms.
