Biological Relationships
Understand the nature of commensalism as a non-harmful coexistence, compared to parasitism (harmful) and mutualism (beneficial to both).

Neutral Impact
Remember that commensals do not provide a benefit to the host like mutualists do.

Shared Habitat
In biology, commensal species often share habitats or living spaces with their hosts.
