Which pairing is an example of a predator-prey relationship?

• A. Egret and rhinoceros
• B. Whale and barnacle
• C. Fox and chicken
• D. Fungi and orchids

Answer: (C)

Predator-prey relationships involve one organism hunting and feeding on another, shaping how energy moves through ecosystems. The fox and the chicken illustrate this: the fox hunts the chicken for food, making the fox the predator and the chicken the prey. This is a classic one-on-one hunting-and-eating dynamic.

The other pairings don’t fit that pattern. An egret and a rhinoceros aren’t a predator-prey pair—the egret may interact with the rhino in non-hunting ways, but the rhino isn’t prey. A whale and barnacle aren’t predator and prey either—the barnacle is a filter feeder that attaches to the whale, not a hunter of it. Fungi and orchids involve symbiotic or parasitic relationships, but not a straightforward predator-prey interaction where one organism hunts and consumes the other.
