The primary source of food for bees is "nectar." Bees collect nectar from flowering plants, which serves as their main energy source. Nectar is a sugary liquid secreted by plants, attracting bees and other pollinators. Once collected, bees convert nectar into honey through a process of evaporation and enzyme action. In addition to nectar, bees also obtain pollen from flowers, which provides essential proteins, vitamins, and fats necessary for their growth and development. The relationship between bees and flowering plants is crucial, as it promotes pollination and biodiversity within ecosystems.
