他们有这些特殊的器官来收集硫化氢和二氧化碳，然后把它们转移到另一个器官，那里有数十亿的细菌。
They have these special organs that collect the hydrogen sulfide and carbon dioxide and then transfer it to another organ, where billions of bacteria live.
这些细菌实际上就是硫化氢和二氧化碳的结合体，而这种化学反应产生的有机物质是更大的有机体的食物。
These bacteria actually combine the hydrogen sulfide with the carbon dioxide and this chemical reaction is what produces organic material which is the food for larger organisms.
正如我们所说，这些热液喷口正在向海洋深处释放这种强热的水，含有一种叫做硫化氢的化学物质，和一种气体，二氧化碳。
As we said, these hydrothermal vents are releasing into the ocean depth this intensely hot water that contains a chemical called hydrogen sulfide, and also a gas, carbon dioxide.
