A sole carbon particle: The degradation of particulate organic matter in the ocean is a central process in the global carbon cycle, the mode and tempo of which is determined by the bacterial communities that assemble on particle surfaces.
Process of photosynthesis makes glucose. Excess glucose is stored as starch, or made into cellulose in cell walls.
