I photographed this bee at the Resaca de la Palma in south Texas. The yellow powder on the under side of the bee is pollen and if you look closely at the rear leg of the bee you will notice a full pollen sack. The bee will take the pollen back to the hive where it will be made into honey. The bees use the honey to feed the young and store it to eat as food, for times that flower nectar is not available.
