Final answer:
Predatory behavior such as prey capture by bluegill sunfish is an example of predation, which is a biological interaction where a predator feeds on its prey.
Step-by-step explanation:
Predatory behavior, such as prey capture by bluegill sunfish, is an ideal example of predation. This biological interaction occurs when a predator organism, like the bluegill sunfish, feeds on another living organism, the prey. The process benefits the predator while often harming the prey, as it can lead to the prey's injury or demise. Predator adaptations, including camouflage and mimicry, help them capture prey, while prey might evolve similar traits to avoid being eaten. However, these are distinct from mutualism, where both species benefit, or competition, where organisms vie for the same resources.
