Answer:
The eukaryotes, bacteria, and archaea that live in and on the human body are called normal microbiota. When they were originally discovered, scientists thought that the relationship between these organisms was parasitic because they thought that the organisms benefit from living on the host but did not help the host. In recent years, researchers have determined that most of our resident microbes derive and give benefit to the host. This makes the relationship between host and microbe one of mutualism. Pathogenic, on the other hand, are microbes that cause diseases.
