《说苑•正谏》中有记载:“园中有树,其上有蝉,蝉高居悲鸣,饮露,不知螳螂在其后也;螳螂委身曲附欲取蝉,而不知黄雀在其傍也;…”虽然这是用以比喻社会现象的寓言,但却反映出生态学中的丰富内容.寓言中所述生物之间的捕食关系,可用下列哪条食物链来表示(  )

A.蝉→螳螂→黄雀

B.露水→蝉→螳螂→黄雀

C.树→蝉→螳螂→黄雀

D.黄雀→螳螂→蝉

答案

从此古文中可以看出里面的生物包括:植物、蝉、螳螂、黄雀.各生物间是吃与被吃的关系:蝉以植物为食,螳螂捕食蝉,黄雀捕食螳螂,植物是生产者,各种动物是消费者.食物链的写法是:起点是生产者,依次是初级消费者→次级消费者→三级消费者→…终点是最高级别的消费者,中间用箭头连接,箭头总是指向捕食者.

A、此链条的起点不是植物,故A不正确;

B、食物链的起点应是绿色植物,而此链条不是,故B不正确.

C、起点是生产者,依次是初级消费者→次级消费者→三级消费者,中间用箭头连接,箭头指向捕食者.故C正确.

D、此链条中没有生产者,箭头的方向相反,故D不正确.

故选:C
