In addition to the movement of carbon through Earth's systems, Francine also wants her model to show how much carbon is stored in reservoirs or sinks. Which of these aspects of the carbon cycle could she add to her model to start building a more quantitative model? Select all that apply. A. The process of photosynthesis moves carbon from the atmosphere to the biosphere. B. About 550 gigatons of carbon is stored in plant biomass. C. The ocean is the greatest carbon sink, storing about 38,000 gigatons of carbon per year. D. Geologic processes such as eruptions move carbon from the geosphere to the atmosphere.

A. The process of photosynthesis moves carbon from the atmosphere to the biosphere.

The ocean is the greatest carbon sink, storing about 38,000 gigatons of carbon per year.

D. Geologic processes such as eruptions move carbon from the geosphere to the atmosphere.

Explanation:

Photosynthesis is a process in which carbondioxide gas that is present in the atmosphere moves into the plant body for the production of food in the presence of sunlight. Volcanic eruption releases high amount of carbondioxide and carbonmonoxide gases in the atmosphere. The ocean is the greatest storage of carbon, storing about 38,000 gigatons of carbon per year.

hi!

it would be because of the artist sixnine.

hope this !

for the points
