Look closely at the Venus flytrap plant at the lower left of the picture. Unlike most plants, the Venus flytrap consumes insects. The plant grows in soil low in nutrients. It has a leaf with hairs that sense an insect landing, causing the leaf to close and trap the insect. Special juices help the plant digest the insect. Which statement describes an adaptation that helps the Venus flytrap live and survive differently than plants that grow in nutrient-rich soil?

• To adapt to its ability to digest insects, the flytrap grows in nutrient-poor soil.

• To live and survive in an environment with many insects, the flytrap consumes insects.

• To survive in nutrient-poor soil, the flytrap has a behavior to get nutrients by consuming insects.

• To survive in nutrient-poor soil, the flytrap has a structure to get nutrients by consuming insects.

Invasive plants compete with local plants for resources. Which statement describes what is likely to happen to local plants that compete with fast-growing invasive plants?

• Their numbers will decrease.

• Their numbers will stay the same.

• Their numbers will increase slightly.
