The best answer choice here will be D! A parasite will live on or in its victim, while a predator will simply attack its prey directly.
The correct answer is option D) One organism is harmed in both parasitism and predation, but out of these two only parasitism involves an organism that coexists with another organism by living on or in it.
In both the interactions i.e. parasitism and predation, one organism is harmed whereas another one is benefited. But, the basic difference in both the interactions is that in predation one organism literally kills another one for obtaining food. While in parasitism, one organism which is being benefited out of another one, lives in close association with it rather than killing it. The organism on/in which the parasitic organism lives is called as host. The parasite uses the host for its survival and also harms it without giving any benefit to it.
