The remaining fixed energy (i.e., mass of photosynthate) is referred to as net primary production (NPP). NPP = GPP - respiration [by plants] Net primary production is the rate at which all the autotrophs in an ecosystem produce net useful chemical energy.
While gross primary production (GPP) is the total influx of carbon into an ecosystem through the photosynthetic fixation of CO 2, net primary production (NPP) is this gross carbon influx ...
Sep 18, 2023 · Net Primary Production (NPP) is a fundamental characteristic of an ecosystem, expressing the conversion of carbon dioxide into biomass driven by photosynthesis. The pixel value represents the NPP for that specific month.
Jan 1, 2021 · Abstract. Primary production provides the organic carbon that ultimately supports the metabolism of autotrophs and heterotrophs in ecosystems. Understanding the pathways that organic carbon follows through an ecosystem leads to distinctions among GPP, NPP, and NEP.

Sep 14, 2022 · Net primary production (NPP) is a major driver of the carbon cycling through the biosphere. Roughly half of the planet’s NPP occurs in the ocean , and quantifying the sources, patterns, and drivers of NPP is therefore a fundamental goal of biological oceanography.
Oct 2, 2020 · This database compiled 11 plant production and ecosystem carbon exchange variables including net primary productivity (NPP), above- and below-ground NPP (ANPP and BNPP), total biomass,...
Jul 20, 2014 · Variation in terrestrial net primary production (NPP) with climate is thought to originate from a direct influence of temperature and precipitation on plant metabolism. However, variation...
