Solution
One organism is benefited, other is affected.
Explanation:
Parasitism is an interaction between two species in which one species (parasite) derives benefit while the other species (host) is harmed. For example, lice (parasites) on the human body and ticks on dogs represent this interaction, where the parasites receive benefits. On the other hand, these parasites reduce host fitness and harm the human body.
