Things which are flammable can get a more (or less) flammable depending on composition (or environment).
For instance furniture is flammable, but if you remove the flame retardants they become a lot more flammable, either the threshold for inflaming is lower, or they burn up a lot faster and / or hotter.

"Falls off" means they decrease not that they disappear, and the lowering nutritiousness of foodstuff is regularly spotlighted.
Admittedly not the most readable construct, but the ">" in the OP's sentence is saying that the plants become more flammable. To the OP, I had not heard that before, would be interested to see those peer reviewed papers if you can share.
> It’s already above 400, so most plants no longer have protein or minerals?
OP said it falls off, not that it goes away completely.
It’s already above 400, so most plants no longer have protein or minerals?
