Question

changes in o2 levels in light and dark bottles can be used to measure ocean net ecosystem production (nep) and gross primary production (gpp) but not net primary production (npp). why is this?

Answer 1

Changes in o2 levels in light and dark bottles can be used to measure ocean net ecosystem production (nep) and gross primary production (gpp) but not net primary production (npp). It is because NPP can't be predicted with out measuring adjustments in CO2 levels.

CO2 flux towers can't degree 0z levels and consequently can't estimate NPP. They degree adjustments resulting from autotrophic respiratory handiest They degree adjustments resulting from heterotrophic respiratory handiest They can't distinguish adjustments resulting from heterotrophic and lalltetrophic respiratory.
