Upchuck does not seem to be able to eat organic and living things, maybe because the bladder dimension seems to reject it causing him discomfort.

In Ben 10 Generator Rex Heroes United, Rex used the power of his omega nanites (controlling other nanites) to compressed the nanites including alpha to becomes a heavy ball of nanites. Rex claimed it to be very heavy and asked how Ben would carry it and Ben changed into upchuck lifted it and ate it. This shows that upchuck rally has strong tounges.

Alpha is like a living thing but actually he is just alpha nanites that is given A.I. which is why even though he was compressed along with the other nanites ben upchuck was still able to eat it
