Nutrient limitation of net primary production in marine ecosystems.
Both gross and net primary production are in units of mass / area / time.
The changes have increased net production in North Korea.
Consequently there is a net production of more reactants (as written).
They generate 32% of the world's net primary production.
They generate nearly 3% of its net primary production.
The two fields combined will enhance Union Pacific's net production by more than 20 million cubic feet a day of natural gas.
The energy remaining after respiration is considered the net primary production.
Where low emissions sources are available, net production of pollutants can be reduced.
Terrestrial freshwater ecosystems generate about 1.5% of the global net primary production.
