Abstract from DBPedia
    In ecology, primary production is the synthesis of organic compounds from atmospheric or aqueous carbon dioxide. It principally occurs through the process of photosynthesis, which uses light as its source of energy, but it also occurs through chemosynthesis, which uses the oxidation or reduction of inorganic chemical compounds as its source of energy. Almost all life on Earth relies directly or indirectly on primary production. The organisms responsible for primary production are known as primary producers or autotrophs, and form the base of the food chain. In terrestrial ecoregions, these are mainly plants, while in aquatic ecoregions algae predominate in this role. Ecologists distinguish primary production as either net or gross, the former accounting for losses to processes such as cellular respiration, the latter not.

    基礎生産(きそせいさん)とは、光合成や化学合成によって、無機物から有機物が生産されることである。 バイオマスをこのような過程で生成する生物(特に植物)は一次生産者として食物連鎖の基底をなしている。 海洋学や陸水学(湖沼学)で使われる基礎生産という言葉は、植物プランクトンが日光のエネルギーを利用して水中でバイオマスを生産する事を指す。微小藻類の細胞は、繊毛虫やカイアシ類、オキアミ等の動物プランクトンに消費され、有機物とエネルギーを供給する。
