The discussion for this week will focus on the importance of thetwo main topics of this chapter (photosynthesis and cellularrespiration) to each other. There is a unique balance between thesetwo energy cycles, and your postings should address somethingspecific that addresses this idea. For instance, you can focus onone of the following: the history of these processes (which one wethink started first and how that eventually led to the other one),different types of interactions, how other things affect them(poisons, temperatures, global climate, etc.), where the organismsare that perform these processes, which organisms have them, thedifferent parts of each one of these and how they are related orhow they came about, or the fact that there are cycles involved andwhat that may indicate. I need an outside source with this with inparagraph citation as well as a reference citing at the end..
