The carbon cycle- (Science) Flashcards
The carbon cycle
The same carbon atoms are used repeatedly on earth. They cycle between the earth and the atmosphere.
What is carbon?
Carbon is an element, the basis of life of earth, found in rocks, oceans, atmosphere
Plants use carbon dioxide-
Plants pull carbon dioxide from the atmosphere and use it to make food- photosynthesis.
Plants use carbon dioxide part 2-
The carbon becomes part of the plant of the plant (stored food).
Animals eat plants-
When organisms eat plants, they take in the carbon and some of it becomes part of their own bodies.
Plants and animals die-
When plants and animals die, most of their bodies are decomposed and carbon atoms are returned to the atmosphere.
Some are not decomposed fully and end up in deposits underground (oil, coal, etc.).
Carbon slowly returns to atmosphere-
Carbon in rocks and underground deposits is released very slowly into the atmosphere.
This process takes many years.
Carbon-
Cycle - repeats over and over and over…
