How do parasites differ from predators?

The key distinction between parasites and predators lies in the nature of their relationship with their hosts or prey. Parasites often rely on a host for a prolonged period, feeding on resources from the host without killing it outright. This contrasts with predators, which typically kill and consume their prey for sustenance.

The correct answer highlights that parasites can affect multiple organisms over time; they may inhabit different hosts at various life stages or reproduce in such a way that they can impact numerous individuals within a population. This characteristic allows them to maintain their life cycle and continue their existence without necessarily killing their hosts, exemplifying a more sustained interaction that can span multiple individuals rather than just one, as seen in predatory behavior.

Other incorrect options do not accurately reflect the established characteristics of parasitic relationships. For instance, the notion that parasites kill their prey instantly oversimplifies their feeding process, which is more gradual and often leads to the prolonged suffering of the host. Additionally, the idea that parasites are larger than their prey is not generally true, as many parasites, such as microscopic worms or protozoa, are significantly smaller than their hosts. Lastly, while a predator may consume several organisms, the key aspect of parasitism is the specific and sometimes exclusive relationship with individual
