Organic carbon: c-containing compounds containing one or more c-h or c-c bonds. Inorganic carbon: c-containing compounds that lack c-h- or c-c bonds (typically contain c-o bonds instead) Photosynthesis: process by which co2 is reduced to organic carbon using energy from sunlight. Respiration: process by which organic carbon is oxidized to inorganic carbon (co2) How to calculate oxidation state of carbon in molecule see lecture 18 slide 7 . Atmospheric co2 shows greater variability in northern hemisphere vs. southern hemisphere. Atmospheric co2 shows greater variability in the northern hemisphere because most of the land on earth is in the northern hemisphere, which means the vegetation of the land will cause more pronounced co2 variability. At steady state, reservoir size remains the same. Renfield ratio (relative number of atoms in phytoplankton): They are dense because of hard mineral shells made of sio2 or caco3.
