Exposure to these organic compounds results in the death of the coral's symbiotic algae.

当珊瑚暴露在这些有机化合物前，会导致珊瑚的共生藻的死亡。

And then, the symbiotic algae that live inside corals-which are photosynthetic food factories-abandon the corals.

之后，珊瑚礁体内的共生藻类，也就是进行光合作用的食物工厂，会抛弃珊瑚。

What happens in bleaching is that these symbiotic algae or tiny plant cells are getting expelled out of the coral tissue.

白化发生的原因，就是这些共生藻类或微型植物细胞被赶出了珊瑚组织。

Organisms as diverse as corals, giant clams and sponges have symbiotic algae living inside their cells, supplying them with organic compounds through photosynthesis.

像珊瑚、砗磲和海绵这样不同的生物都有共生的藻类生活在它们的细胞内，通过光合作用为它们提供有机化合物。

The National Oceanic and Atmospheric Administration or NOAA describes Coral bleaching as Coral expelling its symbiotic algae amid external stressors like changes in water temperature.

美国国家海洋和大气管理局（NOAA）将珊瑚白化描述为珊瑚在水温变化等外部压力下排出共生藻类。

美国国家海洋和大气管理局(NOAA)将珊瑚漂白描述为珊瑚在水温变化等外部压力下驱逐共生藻类。

And a lot of the coloration we're seeing in some of thesecomes from their symbiotic algae.

我们在其中一些身上看到的很多颜色都来自它们的共生藻类。

This is an unfortunate phenomenon where the coral lose their symbiotic algae that produce the food the coral need to survive.

这是一种不幸的现象，珊瑚失去了共生藻类，而这些藻类为珊瑚提供了生存所需的食物。

This March, the authorities responsible for the Great Barrier Reef in Australia announced that the coral reef had experienced a mass bleaching event in which corals expel their symbiotic algae as a reaction to rising temperatures.

今年 3 月，负责澳大利亚大堡礁的当局宣布，珊瑚礁经历了大规模白化事件，珊瑚因温度升高而排出共生藻类。
