What do Carpenter Ants primarily feed on?

Carpenter ants primarily feed on sweets and other insects, making this the correct choice. These ants are attracted to sugary substances, which they often find in honeydew produced by aphids or in other sugary foods left by humans, such as syrup and fruit. In addition to sugars, they also consume protein sources, including other small insects, which contribute to their diet.

Unlike termites, carpenter ants do not feed on wood itself; instead, they excavate wood to create nests. This can sometimes lead to a misconception that they eat wood, but their nutritional needs are met through a varied diet that includes proteins and sugars. Consequently, this behavior highlights their role in the ecosystem, where they can contribute to pest control by preying on smaller insects.

The other options suggest more limited or incorrect diets that do not accurately represent the extensive dietary habits of carpenter ants.
