In this model, which difference best separates predation from parasitism?

  1. Predation kills quickly; parasitism harms a host that usually survivesՃիշտ պատասխան
  2. Predation harms both organisms, while parasitism harms neither
  3. Predation involves only animals, while parasitism involves only plants
  4. Predation happens only between trophic levels, while parasitism happens only inside one level

Բացատրություն

The clearest separation is the outcome for the second organism: a predator kills and consumes its prey, whereas a parasite feeds on a living host that keeps surviving for a time. The claim that predation harms both organisms fails, because the predator gains food from the interaction.
