Some plants are very picky when choosing pollinators. The flowers of European Trollius are like a real safe deposit box, and only six kinds of insects know the code to open the safe deposit box. These lucky people all come from the genus Brevicorn. Only they know how to get into the sepals of European Trollius and find the center of the flower. However, no matter how hard other insects try, they can only fail with disappointment. The short-horned flower fly, which has gone to great pains to pollinate European Trollius, will naturally receive considerable "remuneration". Female short-horned flower flies lay eggs on the carpels of flowers. When the larvae are hatched, they will eat the seeds of flowers and grow up. This symbiotic relationship also has certain risks for European Trollius. The more short-horned flower flies, the greater the chance of pollination, but at the same time, the more insects parasitic on flowers. The cooperative relationship between the two was formed millions of years ago and continues to this day. It is a model of relative balance and harmonious symbiosis in nature.留着性命，我还需要你帮忙呢。因为他曾经说过他憎恨谎言，Tawan开始对此感到尴尬无措，在Tomorn的家里，她经常受到来自于他的母亲Sawai，他妹妹的保姆Gingkaew和暗恋他的秘书Sopit的欺负。Sourceable source1 = new SourceSub1 ();Grayish brown system: solanum, water chestnut, etc.　　文佳煐饰演20代女性的典范、女CEO、医院院长的女儿崔秀智，因其优雅的背景连艺人都和她做朋友。The request is passed on, and from the aspect of performance, the long chain of responsibilities is avoided to improve the performance.
