Final answer:
The flower that consumes insects to obtain nutrients is the carnivorous plant, with the well-known example being the Venus flytrap.
Step-by-step explanation:
The flower that "eats" insects to acquire many of its nutrients is known as a carnivorous plant. These plants have adapted to survive in nutrient-poor environments by evolving specialized leaves to attract and digest insects as a supplementary source of nutrients, especially nitrogen and phosphorus. The Venus flytrap is a well-known example of such a plant. It has leaves that act as traps, using nectar to attract flies and then closing swiftly when a fly touches its sensory hairs. Following closure, the plant secretes digestive enzymes that break down the prey, allowing the plant to absorb necessary minerals.
Apart from the Venus flytrap, there are other carnivorous plants like sundews and pitcher plants, which also employ various ingenious mechanisms to capture and digest their insect prey.
