最近教TAS的学生，刚好教到这章节 以下是Holt Science & Technology教科书上的内容： decomposer: an organism that feeds by breaking down organic matter from dead organisms; examples include bacteria and fungi 一种生物，以分解有机物屍体为食，如：细菌、菌类 内文中提到：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. （整篇懒得翻，请自行参考） === scavenger: an animal that feeds on the bodies of dead animals 一种动物，以动物死屍为食 内文中又提到：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是一种杂食性动物，以动植屍体为食。兀鹰是北美草原上的一种scavenger。 …（中间懒得翻）… scavengers也以自然死亡的屍体为食 ※ 引述《sweet15043 (喵喵绿茶)》之铭言： : 1.年级：国一 : 2.科目：生物 : 3.章节：生态 : 4.题目： : 分解者与清除者 : 5.想法： : 其实没有切确的实际题目 : 我查了生态相关的书 分解者(decomposers)的定义 : 课本写得很武断直接 "the decomposer：bacteria and fungi" : 分解者的定义应该是没什麽疑问 : 我想要查清除者的定义却找不到 只找到 scavenging animal : 清除者是否只是一个方便称呼的名词而已 只是单纯的泛指食腐动物 : 例如秃鹰 埋葬虫....等等 : 在生态学上并没有给予它特别的定义?! -- 我家四只可爱的兔宝宝：） http://www.wretch.cc/album/show.php?i=marraking&b=1&f=1051025995&p=5 --
