In science class, Eric learns about relationships between organisms in
nature. The concepts of predation and parasitism tend to confuse him.
Which explains the difference between these two concepts?
Parasitism results in two organisms benefiting while in predation only one organism
benefits.
Parasitism happens quickly, but predation happens over time.
Predation results in the death of one organism while in parasitism the host may only
be harmed.
Predation and parasitism are the same thing, since only one organism is harmed in
each relationship.

The statement that best explains the difference between the two concepts is predation results in the death of one organism while in parasitism the host may only  be harmed.

Explanation:

Both parasitism and predation are interspecific relationships where one species benefits while the other is harmed or killed.

Parasitism implies the need or dependence that one species has on another, from which it needs to be nourished. It is usually an intimate relationship between parasite and host, a type of symbiosis, where the host usually presents some damage, without implying its death.

In predation, one organism needs another to feed and survive, which means that the affected organism dies in order to become the predator's food.
