How do prey benefit from predation?

Prey do not benefit from predation.

Predation limits the size of the prey population, thus decreasing competition.

Prey learn how to run, swim, or fly faster to avoid being caught.

Predation increases the size of the prey population, thus decreasing the chance that an individual animal will fall prey to a predator.
