(Laughter) These chemolithoautotrophs take the energy that they get from these processes and use it to make food, like plants do.

（笑声） 这些化学自养生物从这些过程中获取能量，并用它来制造食物，就像植物一样。

But the waste product that these chemolithoautotrophs make is often in the form of minerals, like rust or pyrite, like fool's gold, or carminites, like limestone.

但是这些化能自养生物产生的废物通常以矿物质的形式存在，如铁锈或黄铁矿， 如愚人金，或胭脂红，如石灰石。

And the thing that was keeping them underground and keeping it from being released out into the atmosphere was that deep underground, underneath all the adorable sloths and toucans of Costa Rica, were chemolithoautotrophs.
