primary production

In biological contexts, this term refers specifically to the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It is a foundational concept in ecology, serving as the energy base for all subsequent trophic levels in a food web. It is often quantified as gross primary production (GPP) or net primary production (NPP).

In economic and industrial contexts, the term describes the extraction of raw materials. This register focuses on the first stage of the supply chain, distinguishing the gathering of natural resources from secondary production, which involves the processing and manufacturing of those materials into finished goods.
