Reading: 講了生態(tài)學(xué)中的cyclic population change，說在一個生態(tài)系統(tǒng)(ecosystem)中，生物之間的數(shù)量( population)是互相影響的， 捕食者( predator)和被捕食者(prey)的數(shù)量有一個均衡點。
Listening: 教授舉了一個例子來說明：講一種mice和它的predator(可能是某種wolf)之間互相影響。分三個階段：
(l)prey (mice)多，predator食物充足，population增加。
(2)prey少了，predator食物減少了，population減少。
(3)predator少了，prey又開始多起來了，如此循環(huán)，population平衡。教授說實際上第三階段就是第一階段，因為是cyclic，不斷重復(fù)這三個階段。
問題：結(jié)合對話和閱讀材料說說population cycle change的定義和例子。
