问题二：为什么蜻蜓的眼睛是复眼？[^2^]内容如下：

蜻蜓的眼睛是复眼，这是一种由许多小眼组成的眼睛结构。复眼可以让蜻蜓看到更广阔的视野，更清晰地感知运动和颜色，以及更好地适应不同的光照条件。复眼也有助于蜻蜓捕捉飞行中的猎物，躲避天敌，以及与同伴交流。

Translation: Dragonflies have compound eyes, which are a type of eye structure composed of many small eyes. Compound eyes allow dragonflies to see a wider field of view, perceive motion and color more clearly, and adapt to different lighting conditions better. Compound eyes also help dragonflies catch prey in flight, avoid predators, and communicate with mates.
