4. An Ant's Hell: The Hunt for Food 2 蚂蚁的地狱——蚁狮捕食之谜2

This year, Li Hao find a few younger brothers and sisters to continue to explore the ant-lion. They followed up their previous study on the way the ant-lions "defend the well" and the factors that influence their trapping. The biggest factor that affects ant-lion's prey is the size of the trap. This time, they summarized the reasons that affect the size of the trap constructed by ant-lion and did experiments to prove it. Then, by observing the action of sand throwing by ant lions, an experimental device was made to simulate the situation of sand throwing by ant lions, so as to prove that ant lions like to build traps in the sand with smaller grains, and can make the traps bigger and throw the sand farther, so as to attack the prey. 李浩今年找了几位师弟师妹一起继续探究蚁狮。他们接着上期研究蚁狮“守井捕食”的这种方式和蚁狮建构的陷阱捕食的影响因素进行了进一步的探究。 影响蚁狮陷阱捕食最大的因素是陷阱的大小，这次他们总结了影响蚁狮构造陷阱大小的原因并做了实验进行了论证。 然后通过观察蚁狮抛沙的动作，做了实验装置去模拟蚁狮抛沙的情况从而证明蚁狮喜欢在沙粒较小的沙子中建造陷阱，能把陷阱做的更大，能把沙子抛得更远，从而攻击猎物。
