    Male grasshoppers attract females both acoustically and visually.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Male grasshoppers attract females both acoustically and visually. This means that they use both sound and visual displays to attract female grasshoppers for mating purposes. Acoustically, male grasshoppers produce sounds by rubbing their wings or legs together, creating a distinctive chirping sound. This sound serves as a form of communication to attract females. Additionally, male grasshoppers may also use visual displays such as bright colors or elaborate body movements to catch the attention of females. Therefore, the statement "Male grasshoppers attract females both acoustically and visually" is true.
