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?

Predator/Prey relationship

Explanation:

The relationship between Venus flytrap and insect describes a predator/prey relationship with the venus flytrap being the predator while the insect plays the role of prey.

The Venus flytrap is considered a carnivorous plant due to its ability to predate and feed on insects in order to fulfill certain nutritional requirements. It is adequately equipped to sense the presence of insect's movement on its bristles and then trap it by closing the lobes.
