How do organisms function within an ecosystem?
plants
other organisms
trophic levels
photosynthesis
light dependent reactions
light independent reactions
light energy is converted into chemical energy
assemble glucose; requires CO2
cellular respiration
glycolysis
Krebs cycle
ETC
glucose breaks down into pyruvate and energy
oxidizes carbon atoms of the acetyl group of acetyl coenzyme A resulting from the catabolism of lipids, carbohydrates, and proteins to CO2 and transfers the electrons to NAD+ and FAD that transform NADH and FADH2
