Net Primary Productivity
07/13/26
“How do we quantify the rate of new biomass by photosynthesizers after accounting for keeping themselves alive?”
Primary productivity measures the rate of new biomass growth by photosynthesizers. However, these organisms will need to use some of the energy they receive from the sun to keep themselves alive. Consequently, these organisms will only have the Net Primary Productivity, or biomass growth rate, accounting for the energy used to keep themselves alive. Photosynthesizing organisms use the former to grow themselves, and the latter to sustain themselves.
