Why do Venus flytraps trap and digest?

Venus flytraps trap and digest insects primarily to obtain nutrients, particularly nitrogen, which is scarce in their native, nutrient-poor soil. The rapid closure of their modified leaves, which resemble jaws, allows them to capture prey effectively. Once trapped, digestive enzymes break down the soft tissues of the insects, enabling the plant to absorb essential nutrients for growth and survival. This adaptation helps the Venus flytrap thrive in its challenging environment.
