ANS: C w
RATIONALE: Endoparasites live inside the host. Ectoparasites live on the outside of the host.
w w w w w w w w w w w w w
Facultative parasites can live as well outside the host as inside the host; host infection usually
w w w w w w w w w w w w w w w w
occurs accidentally. Other accidental parasites may include parasites that usually infect other
w w w w w w w w w w w w
animals.
