Which of the following statements about fire ants is true?

• A. They are passive and non-aggressive.
• B. They can cause nausea in humans.
• C. They primarily nest in trees.
• D. They do not have any impact on wildlife.

Answer: (B)

The statement that fire ants can cause nausea in humans is accurate based on their characteristic behavior and the effects of their venom. Fire ants are known for their aggressive nature, and when they sting, they inject venom that can lead to a range of reactions in humans. This can include mild symptoms such as local pain and irritation, but in some cases, it can escalate to more systemic responses, including nausea, particularly in individuals who may be more sensitive to their venom or in cases of multiple stings. The other statements do not hold true: fire ants are typically known for their aggressive behavior rather than being passive; they do not primarily nest in trees, as their nests are usually found in the ground; and they do have significant impacts on wildlife, often competing with or preying on other species, thus affecting local ecosystems.
