What sequence represents the correct order of events for production of the necessary complex molecules after food is taken in by a multicellular animal?

Digestion, Absorption, Circulation, Diffusion, Synthesis. 

Digestion begins as soon as you put food in your mouth and begin chewing it, so it is the first step. Absorption happens when food is converted into substances that can be absorbed by your GI tract. Circulation is where those nutrients are circulated in your lymphatic and circulatory system (blood). Diffusion moves oxygen through your blood stream where it gets diffused. Synthesis converts nutrients that have been diffused and absorbed in your blood.
