It is not so difficult to imagine what it means to feedon the organic molecules that living things produce. Thatis, after all, what we do. But what does it mean to “feed” onsunlight, as phototrophs do? Or, even stranger, to “feed” onrocks, as lithotrophs do? Where is the “food,” for example,in the mixture of chemicals (H2S, H2, CO, Mn+, Fe2+, Ni2+,CH4, and NH4+) that spews from a hydrothermal vent?

It is not so difficult to imagine what it means to feed
on the organic molecules that living things produce. That
is, after all, what we do. But what does it mean to “feed” on
sunlight, as phototrophs do? Or, even stranger, to “feed” on
rocks, as lithotrophs do? Where is the “food,” for example,
in the mixture of chemicals (H2S, H2, CO, Mn+, Fe2+, Ni2+,
