TPO 13 Lecture 2 講有關於ecological system 第16題 Why does the proffesor say this? A) To point out that some terms have different meanings in other fields D) To clarify a term used in biology 教授說的 (用""表示) "The term keystone kind of explains itself. In architectute, a keystone in an archway or doorway is the stone that holds the whole thing together and keeps it from collapsing." Well, that's what a keystone species does in an ecosystem. 答案是D 我選的是A 反覆聽幾次還是不解... -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 138.47.114.236
