The best-known carnivorous plant is the Venus flytrap. This amazing plant has a very limited natural habitat: a narrow strip of
land about ten miles wide and one hundred miles long in North and South Carolina. The process that usually happens when an insect lands on a Venus flytrap is this: The insect touches the hairs on the upper side of the leaf blade, triggering a reaction that causes the two halves to snap together. The stiff hairs around the edge of the blade interlock, and the insect is trapped like a prisoner behind bars. Digestive enzymes on the leaf break down the insect’s proteins, and the plant absorbs from its victim the extra nitrogen that it needs. Which action ends the series of events described in the selection?
The insect triggers the hairs on the leaf of the Venus flytrap.
The Venus flytrap digests nitrogen from insect protein.
