What is capitulum in biology?

capitulum An inflorescence that consists of closely packed flowers or florets which have no stalks and arise on a flattened axis, all at the same level.

Do bees eat nectar?

Bees feed on and require both nectar and pollen. The nectar is for energy and the pollen provides protein and other nutrients. Most pollen is used by bees as larvae food, but bees also transfer it from plant-to-plant, providing the pollination services needed by plants and nature as a whole.
