perustuotantona

Perustuotantona is a Finnish expression meaning “as primary production” and is primarily found in ecological and environmental science texts. It refers to the role or function of primary production within an ecosystem and is used to explain processes, relations, or measurements that pertain to the base level of organic matter produced by autotrophs.

In ecology, primary production is the creation of organic matter from inorganic carbon, mainly through photosynthesis by plants, algae, and cyanobacteria, and in some environments through chemosynthesis by bacteria. This production forms the base of the ecosystem’s energy flow and supports all higher trophic levels. When authors describe ecosystem processes or data perustuotantona, they are describing phenomena in the context of this base production that sustains the food web.

Relation to terminology: in Finnish scientific writing, primaarituotanto is the common term for primary production, and perustuotantona appears as a contextual or narrative expression to specify the function of primary production within a discussion. Researchers may refer to gross primary production (GPP) and net primary production (NPP) and express measurements in units such as g C m^-2 yr^-1.
