What do ghost ants primarily feed on?

Ghost ants primarily feed on fatty foods and sweets, which is why this choice is correct. Their diet typically consists of sugary substances, such as honeydew produced by aphids, as well as other sweet materials. They are also attracted to fats, which provide them with the necessary energy. This dietary preference plays a significant role in their foraging behavior and helps them thrive in urban environments where such food sources are readily available.

The other options do not reflect the ghost ants' feeding habits. While they may occasionally scavenge from a variety of food sources, their specific attraction to fatty and sweet foods is a defining characteristic of their dietary needs. This preference enables them to successfully gather food and maintain their colony, particularly in habitats where these resources are abundant.
