Question

in a parasitic relationship, one organism is ______ and one organism is benefiting.
options:
harmed
helped
not effected
happy

Explanation:

In a parasitic relationship, the parasite benefits while the host is harmed. The options "helped" is incorrect (mutualism or commensalism in some cases), "not effected" is incorrect (commensalism for one not affected), and "happy" is irrelevant. So the correct description for the affected organism (host) is harmed.

Answer:

harmed
