Question

How does the Biological carbon pump relate to temperature and salinity? What does it have to do with Nitrogen, silicate and ammonium concentrations?

Answer 1

The bacteria feed on the dead remains, and change the organic carbon back into carbon dioxide, water and mineral nutrients and the transformation of carbon dioxide and nutrients into organic carbon, its sinking into the in the deep ocean, and it's decomposition at depth, is known as the biological carbon pump. Biological carbon pump is affected by the density gradients, in which density in turn affected by the significant change of temperature or salinity.
