2. In the near-surface layers, there are many large, fast carnivores as well as an immense variety of planktonic animals, which feed on plankton (small, free-floating plants or animals) by filtering them from currents of water that pass through a specialized anatomical structure. (TPO45-P3)

在海平面附近,有很多大型的、敏捷的食肉动物以及大量的浮游动物,浮游动物以浮游生物为食(小的浮游植物或动物),这些动物有专门的身体结构过滤海水,吃掉其中的小浮游生物。

3. Although the vast majority of marine fishes are carnivores, in near-surface regions of high productivity the concentrations of larger phytoplankton (the plant component of plankton) are sufficient to support huge populations of filter-feeding sardines and anchovies. (TPO45-P3)

因此,任何能解释食物链底端生物(海洋中的浮游生物、陆地上的植物)毁灭的原因,都能更好地解释在食物链顶端的生物发生了什么,如恐龙的灭绝。
