About 70% of total global carbon is found in:Carbon constitutes about 49 percent of the dry weight of organisms and is next only to water.
Of the total quantity of global carbon, about 71 percent is found dissolved in the oceans.
This oceanic reservoir regulates the amount of carbon dioxide in the atmosphere.
The atmosphere contains only about 1 percent of the total global carbon.
Forests, grasslands and agroecosystems hold carbon in their biomass and soil, but their share is far smaller than that of the oceans.
So about 70 percent of the total global carbon is found in the oceans.
