《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
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
