A Correct answer
Explanation

Predation is an ecological interaction where one organism (the predator) benefits by consuming another organism (the prey), which is harmed or killed. This perfectly matches the description of a stronger partner benefiting and the weaker partner being damaged. Allelopathy involves chemical inhibition, symbiosis involves mutual benefit or close association, and commensalism benefits one partner without affecting the other.
