Which nutrient is primarily derived from pollen for bee development?

The primary nutrient derived from pollen that is essential for bee development is proteins. Pollen is often referred to as the primary source of protein for bees, and it provides the amino acids necessary for growth, development, and maintenance of the bee colony. This includes the development of bee larvae and the overall health of the adult bees. Proteins from pollen contribute to building and repairing tissues, and they play a critical role in producing royal jelly, which is essential for feeding developing larvae and queen bees.

In regards to the other nutrient types, while carbohydrates are mainly sourced from nectar and are crucial for bees as an energy source, fats are not a primary nutrient found in pollen; they are typically derived from other sources. Furthermore, while vitamins are important for bees and can be found in pollen, they exist in smaller quantities compared to proteins. Thus, the significance of protein from pollen for the healthy development and functioning of bees underscores why this option is the most accurate choice.
