Related to primary productivity
The amount of carbon fixed by organisms through the synthesis of organic matter
Sources of energy
Photosynthesis (solar radiation)
Chemosynthesis (chemical reactions)
Influenced by
Availability of nutrients
Amount of solar radiation

Related to primary productivity
Most abundant marine life exists where there is ample
Nutrients
Good sunlight

Productivity in polar oceans
Because of nutrients rising from deeper water, high-latitude surface waters have high nutrient concentrations
Low solar energy limits photosynthetic productivity
