Answer 1

the movement of carbon through living organisms, the atmosphere, the sea, and the earth.

Step-by-step explanation:

The carbon cycle is nature's way of reusing carbon atoms which travel from the atmosphere into organisms in the Earth and then back into the atmosphere over & over again.

Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, the atmosphere, and in living organisms.
