Which of the following is NOT a primary food for deer?

Deer are generally herbivorous animals that thrive on a variety of food sources, primarily focusing on certain types of vegetation that provide them with essential nutrients. Among the options presented, ornamental flowers are not a primary food source for deer. While deer may occasionally nibble on ornamental plants, these flowers are not a significant part of their natural diet.

In contrast, grasses, fruits, and garden vegetables are all common and preferred food items for deer. Grasses are abundant in natural habitats and provide deer with necessary fiber and energy. Fruits, especially in late summer and fall, serve as an important nutrition source due to their high sugar content. Garden vegetables, when accessible, are also actively consumed by deer, especially during seasons when natural forage is scarce or when they wander into gardens.

Therefore, ornamental flowers can be categorized as non-primary food sources for deer, making this choice stand out from the others, which represent typical and nutritious elements of their diet.
