Predation vs. Parasitism: What's the Difference?
Edited by Huma Saeed || By Sumera Saeed || Updated on October 27, 2023
Predation is an interaction where one organism (predator) kills and eats another (prey). Parasitism is a relationship where one organism (parasite) lives on or in a host, harming but usually not killing it.
Key Differences
Predation involves a predator killing and consuming its prey, directly affecting population dynamics. Parasitism, however, involves a parasite living off a host, often causing harm but not immediate death.

In predation, the predator-prey relationship typically results in the death of the prey. In parasitism, the parasite-host relationship allows both to survive, though the host may suffer harm.

Predators are usually larger than their prey and engage in active hunting or trapping. Parasites are often smaller than their hosts and rely on them for nutrients, often living on or inside them.

Predation plays a crucial role in controlling prey populations and maintaining ecological balance. Parasitism can lead to host diseases but also contributes to ecological balance by controlling host populations.

Predators are independent and their survival depends on successfully capturing prey. Parasites depend on their hosts for survival, often having complex life cycles involving multiple hosts.
