 It may not be immediately obvious that this forest fire down below and this moose in Glacier National Park up above are in some sense doing the same thing biochemically, but they are. The moose, it's called respiration, and down here it's called a fire, a conflagration. But what they're doing is taking plant, adding oxygen, and using that to cause chemical reactions that release energy, which you see as the heat and light here, or you see as the moose able to stand up and chew and run around and do moose things.
