3-6 What Happens to Matter in an Ecosystem !?
[翻譯的部份]
Nutrient cycles connect past , present , and future forms of life . Some of the carbon
atoms in your skin may once have been part of a leaf , a dinosaur's skin , or a layer of li-
mestone rock . Your grandmother , Attila the Hun , or a hunter-gatherer who lived 25000
years ago may have inhaled some of the oxygen molecules you just inhaled.
[中文]
營養的循環連結著過去、現在、未來而形成生命。有一些碳原子在你的皮膚、恐龍
的皮膚,有可能以前是葉子的一部份、或者是一層石灰石。
[大意]
大意是物質是一直循環著的。有可能我們現在呼吸的氧分子,可能是之前祖先呼吸過的
,所以這個世界真是太奧妙了!!! 哇哈哈 !! XDD
