Organisms living on or inside another organism are called?

• A. Parasites
• B. Infectious Disease
• C. Infection
• D. Staphylococci

Answer: (C)

Parasites are organisms that live on or inside another organism (the host) and depend on it for nourishment, often harming the host in the process. This includes organisms that inhabit the host’s body or surface, such as tapeworms and mites, as well as protozoa that invade tissues. This idea is distinct from infection, which refers to the invasion and multiplication of microorganisms in the host, and from infectious disease, which is the illness that results. Staphylococci are a specific type of bacteria that can cause infections, but they illustrate a cause of disease rather than the general term for organisms living in or on a host. So, the term that fits the description is parasites.
