You're still clinging to an origin story which has no bearing on the character and which Tyrant has never shown ability to drain in combat except with Galactus machine to extreme?
Dude, enough is enough. Haven't you been schooled already on that several times?
Biosphere is the medium through which life force energy can exist. In other words, it's the perfect conditions for life. They are certainly different. Way to ignore my post though.
But let's use your own logic -- which dictates that life force is the same as BSE:
Odin can, and has, manipulated life force (here is another example, apart from the Celestials instance, of Odin casually manipulating Thor's life force/spirit http://imgur.com/a/AancO).
So that means Odin can just as easily drain Tyrant's Biospheric energies (which you seem to be equating with life force).
