Question

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?
competition
parasitism
predation
commensalism

Explanation:

1. Competition: Occurs when organisms compete for the same resources (like food, space). The Venus flytrap and the insect are not competing for a resource; the flytrap is consuming the insect, so this is incorrect.
2. Parasitism: A relationship where one organism (parasite) benefits at the expense of another (host), and the host is usually not killed immediately or is kept alive for the parasite's benefit. The Venus flytrap kills and digests the insect, so this is not parasitism.
3. Predation: A relationship where one organism (predator) kills and eats another (prey). The Venus flytrap (predator) captures, kills, and digests the insect (prey) for nutrients, which fits predation.
4. Commensalism: A relationship where one organism benefits and the other is neither helped nor harmed. The insect is harmed (killed) here, so this is incorrect.

Answer:

C. predation
