Which of the following statements about crop planting in rights of way is true?

The statement that planting in rights of way can lead to competition with native species is correct because introducing crops, especially non-native ones, can alter the local ecosystem. Non-native plants may grow aggressively, outcompeting native flora for resources such as light, water, and nutrients. This competition can disrupt the natural habitat, leading to a decline in biodiversity and negatively impacting local wildlife that depends on native plants for food and shelter.

In contrast, while the planting of food crops might promote biodiversity in some scenarios, it often depends on the specific context and the species involved. It's also not a widely accepted cultural control technique, and it certainly has ecological impacts that can be detrimental rather than benign. Hence, recognizing the competitive nature of crops with native species is essential for understanding the potential ecological consequences of planting in rights of way.
