Generally, the major factor that limits primary productivity in most oceans is
1 Oxygen
2 Water
3 Nutrients
4 \(\mathrm{CO}_{2}\)
Explanation:
Nutrients (nitrogen, phosphorus and iron) limit primary production in most oceans and lakes.Concentrations of these nutrients are typically lowin the photic zone because they are rapidly taken up by phytoplankton and because detritus tends to sink.

Net primary productivity (NPP) is given by the formula
1 \(\mathrm{NPP}=\mathrm{GPP} \times \mathrm{R}\)
2 \(\mathrm{NPP}=\mathrm{GPP}-\mathrm{R}\)
3 \(\mathrm{NPP}=\mathrm{GPP}-\mathrm{R} / 100\)
4 \(\mathrm{NPP}=\mathrm{GPP} \times 100\)
Explanation:
\(\mathrm{NPP}=\mathrm{GPP}\) - \(\mathrm{R}\) is correct

The annual net primary productivity of the whole biosphere is approximately____ tons (dry weight) of organic matter. Of this, despite occupying about____ of the surface, the productivity of the oceans are only____ tons.
1 55 billion, 70 per cent, 55 billion
2 170 million, 70 per cent, 55 million
3 55 million, 70 per cent, 55 million
4 170 billion, 70 per cent, 55 billion
Explanation:
The annual net primary productivity of the whole biosphere is approximately 170 billion tons (dry weight) of organic matter. Of this, despite occupying about 70 per cent of the surface, the productivity of the oceans are only 55 billion tons.

Identify the correct formula regarding NPP and GPP
Net primary productivity is gross production minus the losses by the way of respiration and decomposition. Gross primary productivity of an ecosystem is the rate of production of organic matter during photosynthesis.
