Question

What is microbiota in the context of commensalism?

विकल्प

• Microorganisms that compete with the host for resources

• Microorganisms that break down the host's tissues

• Harmless microorganisms colonising host surfaces

• Harmful bacteria that infect the host organism

Answer 1

Microbiota refers to harmless microorganisms that colonize the surfaces of a host organism. These microorganisms benefit from the surface environment and resources of the host but do not cause harm. An example is the skin microbiota found on mammals, which exists in a commensalistic relationship with the host.
