"浮游植物生活在海洋表面，在那里他们把二氧化碳释放到海里，同时放出氧气。
Phytoplankton live at the ocean surface, where they pull carbon dioxide into the ocean while giving off oxygen.
在一些水域，比如北极，气候变暖会使浮游植物生长成熟，而这些区域会变得更绿。
In some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener.
在世界上所有的海洋，包括北冰洋，尾海鞘都是出没在浮游植物密度最大的水域表面。
Found in all the oceans of the world, including the Arctic Ocean, appendicularians tend to remain near the water's surface where the density of phytoplankton is greatest.
气候变化将加速某些地区浮游植物的生长，同时减少其他地区的浮游植物，导致海洋的外观发生变化。
Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean's appearance.
人们提出了许多理论来解释食草动物，如浮游动物，在控制浮游植物高度集中地区的食草动物方面所起的作用。
Many theories have been formulated to explain the role of grazers such as zooplankton in controlling the excluded grazers from regions of high phytoplankton concentration.
虽然后来的实验证实，这种方法增加了浮游植物的生长，但实地试验表明，这种生长不会显著降低大气中的二氧化碳。
While experiments subsequently confirmed that such a procedure increases phytoplankton growth, field tests have shown that such growth does not significantly lower atmospheric carbon dioxide.
气候变暖改变了海洋的主要特征，并会影响浮游植物的生长，因为它们不仅需要阳光和二氧化碳才能生长，而且还需要营养。
Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
年幼的刺冠海星在出生后的第一个月就以浮游植物为食，所以海洋中肥料越多，浮游植物就越多，也意味着海星越多，这对珊瑚礁非常不利。
Larval CoT starfish eat phytoplankton in their first month of life, so more fertilizer in the ocean means more phytoplankton, which means more starfish, bad for the reefs.
浮游植物是生长在海里的微小植物。
Phytoplankton are microscopic plants that grow in the ocean.
浮游植物也可以是死亡或疾病的先兆。
Phytoplankton can also be the harbingers of death or disease.
杀光浮游植物就和把陆地上的草全拔了一样。
