more energy info
I am supposed to tell y'all about how energy moves through our planet and it's inhabitants.
We have two main heat energy sources: the sun and the earth. Unfortunately, the earth's heat can't support life on its own, so we're totally dependent on the Sun. Which will go out. Pretty scary, huh?
Anyway, the Sun produces heat and light and sends it to earth in the form of infrared radiation. Well, the heat. That thermal energy goes into plants, which use it and light and carbon dioxide to make carbon stores/sugar stores. Somehow they take CO2 and change it into carbon.
That is where animals come in. See, the rabbit (or cow, or horse, take your pick) eats the plant and takes THOSE carbon stores and adds them to itself. Then along come people and eat the rabbit/cow/horse to get those carbon stores into ourselves.
We are made out of the sun, in a way
