What are the four types of The four types of symbiosis are mutualism
symbiosis? (both species benefit), commensalism (one
species benefits, the other is unaffected),
parasitism (one species benefits at the
expense of the other), and amensalism (one
species is harmed while the other is
unaffected).

What is the relationship among A parasite is an organism that lives on or in a
parasite, host, and pathogen? host and benefits at the host's expense. A
pathogen is a type of parasite that causes
disease in the host.


What is the microbiome? The microbiome is a community of
microorganisms residing in a specific
environment, such as the human body,
which includes resident members
(permanently present) and transient
members (temporarily present).


What conditions create Three conditions include: (1)
opportunities for normal immunocompromised state of the host, (2)
microbiota to cause disease? introduction of normal microbiota to an
