Chapter 27, Problem 7U
Summary Introduction
Introduction: The nutritional strategies of prokaryotes were classified based on carbon, electron, and energy sources. Carbon sources include atmospheric carbon dioxide or reduced carbon from the environment. The energy sources include light and reduced organic or inorganic compounds. The electron sources include reducing organic or inorganic compounds.
