Question

which symbiotic interaction involves one animal killing and eating another?
predation
commensalism
competition
mutualism

Explanation:

To solve this, we analyze each option:

• Predation: Defined as one organism (predator) killing and consuming another (prey).
• Commensalism: One organism benefits, the other is unaffected (no killing/eating).
• Competition: Organisms compete for resources (no killing/eating of one by another in this context).
• Mutualism: Both organisms benefit (no killing/eating).

So predation matches the description.

Answer:

A. predation
