…RH Whittaker has compiled these data to estimate the energy efficiency of primary producers on Earth, which is 0.6% for gross production and 0.27% for net production, revealing that the amount of solar energy available to humans as consumers is surprisingly small. LB Slobodkin has also estimated that the ecological efficiency of animal populations is mostly in the 5-20% range. The ecological pyramid can be said to illustrate these ecological efficiencies. … *Some of the terminology that mentions "Slobodkin, LB" is listed below.

…ホイッタカーR.H.Whittakerはこれらの資料をまとめて地球上の一次生産者によるエネルギー効率を推定しているが,それによると総生産では0.6%,純生産では0.27%となっており,消費者である人間が利用できる太陽エネルギーが意外に少ないことが明らかとなった。また,スロボトキンL.B.Slobodkinは,動物個体群における生態効率は,5~20%に大部分が入ることを予測している。生態的ピラミッドは,これらの生態学的効率を図示しているものといえよう。… ※「Slobodkin,L.B.」について言及している用語解説の一部を掲載しています。 出典|株式会社平凡社世界大百科事典 第2版について | 情報 |
