From the Ted Talk by Karen Lloyd: The mysterious microbes living deep inside the earth -- and how they could help humanity
Unscramble the Blue Letters

These cotphhmotaoiorehults take the energy that they get from these processes and use it to make food, like plants do. But we know that plants do more than just make food. They also make a waste product, oxygen, which we are 100 percent dependent upon. But the waste porcudt that these chemolithoautotrophs make is often in the form of minerals, like rust or pyrite, like fool's gold, or carminites, like limestone. So what we have are microbes that are really, really slow, like rokcs, that get their energy from rocks, that make as their waste product other rocks. So am I talking about biology, or am I tlnakig about geology? This stuff really bulrs the lines.
