Answer:Carbon moves from living things to the atmosphere. Each time you exhale, you are releasing carbon dioxide gas (CO2) into the atmosphere. Animals and plants need to get rid of carbon dioxide gas through a process called respiration. Carbon moves from fossil fuels to the atmosphere when fuels are burned. 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 and over again. Most carbon is stored in rocks and sediments, while the rest is stored in the ocean, atmosphere, and living organisms.

First of all, this was a bit garbled up, so it is sort of incomplete.
You gave me a total of 43 words, and I only counted 41 slots on the crossword graph itself, which is problematic.
I got as far as I could, but some of the words either weren't provided, or the spaces were made incorrectly for the length of these words.
