Which of the following is NOT a food source for bees?

Bees primarily obtain their food from sources that provide them with carbohydrates, proteins, and lipids necessary for their survival and nourishment. Flower nectar is a vital source of sugar and moisture, while pollen serves as their primary source of protein. Additionally, honeydew—excreted by certain insects like aphids—can also be a food source for bees as it is rich in sugars.

Insects and spiders, on the other hand, do not constitute a typical food source for bees. While bees may occasionally consume some protein from dead insects or larvae, they do not actively hunt or feed on live insects and spiders. Instead, their diet is predominantly plant-based, relying on the sugary fluids from flowers and the protein found in pollen. This distinction underscores why the listed option of insects and spiders is not considered a food source for bees.
