What is the term for the rate at which biomass accumulates in an ecosystem?

Explanation:
Net Primary Productivity is the rate at which biomass accumulates in an ecosystem. It represents the amount of carbon fixed by photosynthesis minus what plants respire, so it reflects the actual gain in plant biomass available for growth and for consumers. Gross Primary Production, by contrast, is the total carbon fixed before respiration, which overstates the material that remains as biomass. The term “Productivity” is too general and could refer to various processes, not specifically biomass accumulation, and Landscape Ecology is a field focusing on spatial patterns rather than a rate of biomass growth. Net Primary Productivity is typically expressed in units like g C m^-2 yr^-1 and directly describes the biomass buildup over time.
