Answer: Light intensity

Explanation:

The total amount of nutrient( organic material) which is left after respiration, in order to support the other levels of the food chain is known as the net primary productivity.

More than 90% of the producers are the pytoplanktons that performs the process of photosynthesis.

The intensity of light falling on the water surface affects the rate of primary productivity.
