My 10mnths baby refuses to breastfeed for the whole day & she cries a lot.she bites the nipple whenever i try to feed her.no temperature. what could be the problem?

Check BM, see Ped: Check your breastmilk supply - make sure that you are not engorged and your flow is not too fast for the baby. Sometimes when the flow is too fast, the baby has to clamp the nipple to stop the flow. If this is the case, manually pump to release the pressure and try again. Make sure she still has wet diapers/drooling. If these are significantly decrease need to see Peds.
