我要喝可乐

Which of the following most logically completes the argument?
By competing with rodents for seeds, black ants help control rodent populations that pose a public health risk. However, a very aggressive species of black ant, the Loma ant, which has recently invaded a certain region, has a venomous sting that is often fatal to humans. Therefore, the planned introduction into that region of ant flies, which prey on Loma ants, would benefit public health, since.

(A)        ant flies do not attack black ants other than Loma ants
(B)        Loma ants are less effective than many bird species in competing with rodents for seeds
(C)        certain other species of black ants are more effective than Loma ants in competing with rodents for seeds
(D)        the sting of Loma ants can also be fatal to rodents
(E)        some pesticides that could be used to control Loma ants are harmful to the environment
正确答案A

想问一下第一句话到底怎么翻译啊，难道是：为了与啮齿类动物竞争获得种子？还是为了和啮齿类动物竞争获得后代？
请指教！多谢！

compete for 有为夺取的意思，所以我觉得此处应该为种子，也许是一种食物。
不过文章很短没有上下文可以对照，此处又非关键点，这样猜测词义意义不大
