carbonic = carb(碳) + on(人，物) + ic(…的) = 碳的
carbonization = carb(碳) + on(人，物) + ization(…化) = 碳化
漂泊的动物→浮游动物
plankton
常考释义
n. 浮游生物【生】
The bugs sustain not only the plant, but an intricate food web of bacteria, plankton and invertebrates.
这些怪物不仅供养着植物，而且是由细菌、浮游生物和无脊椎动物组成的一个复杂的食物网。
Some are likely toxins, such as those released by the dinoflagellates (a species of plankton) during red tides, which inhibit growth of other photosynthetic organisms.
一些是类似于毒物，比如由腰鞭毛虫在赤潮中释放的物质。这种物质会抑制其他光合作用的有机物。

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。
来源于：阅读OFFICIAL45 P3Although 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.
虽然绝大多数海洋鱼类是食肉动物，但滤食性沙丁鱼和凤尾鱼靠吃海洋表面区域丰富大量的浮游植物（浮游生物的植物成分）而大量繁殖。
来源于：阅读OFFICIAL45 P3It wiped out many kinds of plankton in the ocean and many marine organisms that lived on the plankton at the base of the food chain.
有许多海洋中的浮游生物都灭绝了，而以这些处于食物链的底端的浮游生物为食的许多海洋生物也都灭绝了。
来源于：阅读OFFICIAL42 P2So any event that can explain the destruction of the base of the food chain (plankton in the ocean, plants on land) can better explain what happened to organisms at the top of the food chain, such as the dinosaurs.
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。
