To what degree are gods dependent on worship for their strength?

This is just something that I was curious about but haven’t found too much information on. In Morrowind, Vivec states that he first opposed the Nerevarine and the dissident priests because it was necessary for the people of Morrowind to continue worshipping the Tribunal so that they could maintain the amount of power and control that they had left. He implies that the Tribunal may have been unable to keep the Ghostfence in place without the continued worship of the people. So if the Tribunal, and presumably the other divines, are dependent on the worship of people for their power, to what degree? It seems that the Daedra have power whether they are worshipped or not, but for some reason the Aedra and other gods require at least some degree of worship for their power to manifest. Is there any in-game dialogue or information that goes more in-depth about this topic? Or maybe even some obscure Kirkbride forum post from 10+ years ago?
