The correct answer to this question would be:
The microorganisms that make up the
normal human flora are important for “preventing the colonization and multiplication of pathogens”.
The human flora or human microbiota is
the totality of microorganisms which resides on or within our body. The normal flora of humans is composed of a few
eukaryotic fungi and protists, but bacteria are the most abundant and obvious
microbial components of the normal flora. The microorganisms of the
normal flora help the body fights against the pathogens by challenging for
microenvironments more effectively than such pathogens or by supplying
nutrients the body can use.
