Bees get both nectar and pollen from flowers. Nectar is a mixture of water and sugars produced by plants, and it provides bees with energy. Pollen, on the other hand, is a source of protein and other nutrients that bees need to feed their developing offspring. Bees collect pollen from flowers by landing on them and gathering it with their tiny hairs. They then transfer the pollen to the next flower they visit, which allows for cross-pollination and the reproduction of plants. In this way, bees play a crucial role in the ecosystem by pollinating plants and helping them to reproduce.
