James (Jim?), There's something VERY strange about this because, as Stan said, the D7000 does ***NOT*** have the ability to supply power to an external microphone. FWIW, nor does any of Nikon's other video-capable cameras.
My STRONG advice is to rely upon the microphone's battery as any other apparent power source could easily disappear.
EDIT: OK, so the ME-1 specification DEFINITELY indicates that it is an electret mic. whose power comes from the camera.
I have just measured a +2.5VDC bias on each of the mic. inputs of my D4, so an Electret mic. CAN be powered reliably by, at least some, Nikon bodies...
Stan: Everything seems to point to the fact that we were both WRONG!
James: I now believe that you CAN rely on powering the mic. from the camera.
