Which interaction involves one organism killing and consuming another for food?

• A. Commensalism
• B. Predation
• C. Mutualism
• D. Parasitism

Answer: (B)

This question tests understanding of feeding-related interactions in ecology. Predation is when one organism kills another and then eats it for nourishment. That direct kill-and-consume dynamic is why this option is the best choice. The other relationships describe different kinds of associations: commensalism is when one benefits and the other is unaffected; mutualism is when both benefit; parasitism is when one benefits by living on or inside the host and typically harms it, though not usually by killing the host to feed on it.
