d. Facultative parasite GRADESMORE.COM
ANS: C
RATIONALE: Endoparasites live inside the host. Ectoparasites liveJon the outside of the host. Facult
ativeJparasites can live as well outside the host asJinside the host; host infection usually occurs accide
ntally. Other accidental parasites may include parasites that usually infect other animals.
