All of the topics within the DCQs can be reduced to three basic principles?: generation?, transformation?, and oxidation? of organic carbon. In parentheses are typical applied processes? within college Biology curricula that fall under each basic process. By helping students to categorize specific topics under a more general process, they will be better able to see similarities between topics and make knowledge transfers. 1) Generation (photosynthesis, primary production) 2) Transformation (building of biomolecules within an organism, consumption of one organism by another, defecation, root exudation) 3) Oxidation (autotrophic respiration, heterotrophic respiration, decomposition, combustion of fuels, weight loss, greenhouse gas accumulation
