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?

you have embarked on an ambitious research project: to create life in a test tube. you boil up a rich mixture of yeast extract and amino acids in a flask along with a sprinkling of the inorganic salts known to be essential for life. you seal the flask and allow it to cool. after several months, the liquid is as clear as ever, and there are no signs of life. a friend suggests that excluding the air was a mistake, since most life as we know it requires oxygen. you repeat the experiment, but this time you leave the flask open to the atmosphere. to your great delight, the liquid becomes cloudy after a few days and under the microscope you see beautiful small cells that are clearly growing and dividing. does this experiment prove that you managed to generate a novel life-form? how might you redesign your experiment to allow air into the flask, yet eliminate the possibility that contamination is the explanation for the results? (for a ready-made answer, look up the classic experiments of…
Which of the following statements is true of chemoautotrophs? O They use hydrogen sulfide as their hydrogen source for the photosynthesis of their organic compounds. O They "feed themselves" by obtaining energy from the chemical bonds of organic molecules. O They oxidize inorganic compounds to obtain energy to drive the synthesis of their organic compounds. O They live as decomposers of inorganic chemicals in organic litter. O They obtain their energy from oxidizing chemical compounds and get their carbon skeletons from organic compounds.

The water in theYellowstone NationalPark hot springs shownhere is around 160°F(70°C). Biologistsassumed that no speciesof organisms couldlive in water aboveabout 130°F (55°C), sothey were surprisedto find several speciesof bacteria there, nowcalled thermophiles(“heat-lovers”). You’ve learned in this chapter how an enzymefrom one species, Thermus aquaticus, made feasible one of themost important DNA-based techniques used in labs today.Identify the enzyme, and indicate the value of its being isolatedfrom a thermophile. Suggest other reasons why enzymes fromthis bacterium (or other thermophiles) might also be valuable
