And the bacteria, well the bacteria kind of feed the tube worms through chemosynthesis, remember, that chemical reaction I described earlier.

细菌，嗯，细菌通过化学合成喂养管虫，记住，我之前描述的化学反应。

Around these vents, communities of organisms have evolved that rely on chemosynthesis--a process where bacteria derive energy from chemical reactions instead of sunlight.

在这些喷口周围，生物群落的进化依赖于化学合成——细菌从化学反应而不是阳光中获取能量的过程。

At the mid--ocean ridges, hydrothermal vents support unique ecosystems, where organisms derive energy from chemicals spewed out of the vents, a process known as chemosynthesis.

在大洋中脊，热液喷口支撑着独特的生态系统，生物体从喷口喷出的化学物质中获取能量，这一过程被称为化学合成。

This was a living system based not on photosynthesis but on chemosynthesis, an arrangement that biologists would have dismissed as preposterous had anyone been imaginative enough to suggest it.

这种生命体系的基础不是光合作用，而是化学合成。要是哪个想像力丰富的人提出这种安排，生物学家们肯定会认为是很荒谬的。

These bacteria that live inside the tube worms, the tube worms provide them with hydrogen sulfide and carbon dioxide. And the bacteria, well the bacteria kind offered the tube worms through chemosynthesis, remember, that chemical reaction I described earlier.

这些生活在管虫体内的细菌，管虫为它们提供硫化氢和二氧化碳。还有细菌，嗯，这种细菌通过化学合成提供了管虫，记住，我之前描述的化学反应。
