最近教TAS的學生，剛好教到這章節 以下是Holt Science & Technology教科書上的內容： decomposer: an organism that feeds by breaking down organic matter from dead organisms; examples include bacteria and fungi 一種生物，以分解有機物屍體為食，如：細菌、菌類 內文中提到：Decomposers are organisms that get energy by breaking down dead organisms are called decomposers. Bacteria and fungi are decomposers. These organisms remove stored energy from dead organisms. They produce simple materials, such as water and carbon dioxide, which can be used by other living things. Decomposers are important because they are nature’s recyclers. （整篇懶得翻，請自行參考） === scavenger: an animal that feeds on the bodies of dead animals 一種動物，以動物死屍為食 內文中又提到：Scavengers are omnivores that eat dead plants and animals. The turkey vulture is a scavenger in the prairie. A vulture will eat what is left after a coyote has killed and eaten an animal. Scavengers also eat animals and plants that have died from natural causes. Scavenger是一種雜食性動物，以動植屍體為食。兀鷹是北美草原上的一種scavenger。 …（中間懶得翻）… scavengers也以自然死亡的屍體為食 ※ 引述《sweet15043 (喵喵綠茶)》之銘言： : 1.年級：國一 : 2.科目：生物 : 3.章節：生態 : 4.題目： : 分解者與清除者 : 5.想法： : 其實沒有切確的實際題目 : 我查了生態相關的書 分解者(decomposers)的定義 : 課本寫得很武斷直接 "the decomposer：bacteria and fungi" : 分解者的定義應該是沒什麼疑問 : 我想要查清除者的定義卻找不到 只找到 scavenging animal : 清除者是否只是一個方便稱呼的名詞而已 只是單純的泛指食腐動物 : 例如禿鷹 埋葬蟲....等等 : 在生態學上並沒有給予它特別的定義?! -- 我家四隻可愛的兔寶寶：） http://www.wretch.cc/album/show.php?i=marraking&b=1&f=1051025995&p=5 --
