It's like, you're no longer keeping score in those ways.

就像，你不再以这些方式记分。

If lionfish are preying on parrot fish, those parrot fish are no longer keeping the reefs clean and a lot of times the algae can overtake the reef and cause a bunch of coral death.

如果狮子鱼捕食鹦鹉鱼，那么这些鹦鹉鱼就无法再保持珊瑚礁的清洁，而且很多时候，藻类数量会超过珊瑚礁，从而导致大量珊瑚死亡。
