The snottites described in the case "The First Cell: Life's Origin" at the beginning of Chapter 2 are colonies of bacteria, which are extremophiles that have some unique requirements for life processes. For example, they use sulfur from the hydrogen sulfide in the environment to capture energy. Although most life forms that are familiar to you, including humans, don't use sulfur for this purpose, we do use another element to do the same thing. Which element do humans use for this energy conversion? Carefully examine the periodic table.
