Which of these characteristics is NOT true about deer?

Deer are herbivores that primarily feed on a variety of plant materials, including leaves, fruits, and nuts. While they do enjoy nuts when available, the question focuses on identifying a characteristic that is not commonly attributed to deer behavior. The other options highlight more typical interactions that deer have with their environment, such as trampling trees, damaging shrubs, and rubbing their antlers against trees to mark territory and remove velvet. These actions are well-documented in wildlife behavior studies, indicating how deer can impact their ecosystems. However, feeding on nuts does not represent a distinct or defining behavior that sets deer apart, as many other animals also consume nuts. Therefore, the characteristic of feeding on nuts may not be as directly impactful or specific to deer as the other interactions listed.
