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
