Which sentence correctly describes Kudzu?

• A. A native US plant used for soil stabilization
• B. Invasive plant native to Asia introduced as ornamental; now overcrowds native species
• C. A fungal disease that affects trees
• D. A herbicide used to control weeds

Answer: (B)

Invasive species are non-native organisms that spread rapidly and outcompete native plants, often changing habitats and reducing biodiversity. Kudzu is a classic example of this pattern. It originated in Asia and was brought to the United States for ornamental use and for soil erosion control. Because it grows extremely quickly and can climb over and shade out other vegetation, it has become established in many areas and crowds native species. That combination—originating from Asia, being introduced for human purposes, and now dominating ecosystems—best describes Kudzu.

The other descriptions don’t fit: Kudzu isn’t a native U.S. plant, it isn’t a fungal disease, and it isn’t a herbicide.
