Which of the following is NOT a characteristic of a noxious weed?

• A. Harmful to public health
• B. Threatens natural habitats
• C. Beneficial for agriculture
• D. Destructive to local ecosystems

Answer: (C)

A noxious weed is defined as a plant that is harmful to the environment, agriculture, or public health. The presence of such plants typically leads to negative consequences, including the disruption of local ecosystems, competition with native species, and impacts on agricultural productivity. The correct response highlights that noxious weeds are not characterized as beneficial for agriculture. In fact, they often outcompete native crops or desirable plants, leading to reduced yields and increased management costs for farmers. Their invasive nature means they thrive in conditions that may be detrimental to cultivated crops, thus confirming their classification as harmful rather than beneficial. In contrast, the other options reflect the characteristics commonly associated with noxious weeds. They can pose risks to public health, threaten natural habitats, and disrupt local ecosystems, contributing to ecological imbalance and biodiversity loss.
