Short-term carbon cycle Flashcards
What is the short-term carbon cycle?
Movement of carbon through the biosphere
How much more carbon does the short-term carbon cycle move than the long-term?
100-1,000 times more carbon and does it faster
How does carbon move through the short-term carbon cycle?
Plants absorb carbon dioxide through photosynthesis and uses energy from the sun to turn it into carbohydrates and release oxygen
What else photosynthesises?
Phytoplankton in the oceans
How else does carbon move through the short-term carbon cycle?
Animals respiring and releasing methane when digesting food.
Decomposition of dead organisms.
Fires release carbon back into the atmosphere.
How much carbon moves through the short-term carbon cycle each year?
Between 1,000 million to 100,000,000,000 metric tons
Where are huge carbon stores?
Peat soils are very wet meaning there is little oxygen in the soil which stops decomposition
