When an insect touches the bristles on the lobes of a Venus flytrap, the lobes close quickly, engulfing the insect. The movement of the insect inside the lobes causes the flytrap to secrete digestive enzymes that kill the insect. Which type of relationship does this describe?

The Venus flytrap captures and kills the insect, then digests it for nutrients. An organism that kills and consumes another organism is a predator, so this is predation. Competition involves organisms trying to use the same limited resource, while parasitism and commensalism describe relationships where one organism lives with or on another.
