Answer:
here.
Step-by-step explanation:
Carbon dioxide in the atm is taken up by the plants by diffusion through the stoma for photosynthesis. In the presence of sunlight energy and water, it'll be converted in the chlorophyll into glucose, and oxygen as a byproduct.
When organisms eat the plants, they gain the glucose stored as starch in the plants. Glucose is going to be used for the aerobic (also anaerobic) cellular respiration. It undergoes glycolysis where it's cleaved into 2 pyruvate molecules that get converted into 2 acetyl~CoA molecules that enter the Kreb's cycle.
The reduced NAD+ and FAD will get oxidized in the electron transport chain. ATP synathase will then oxidatively phosphorylate ADP to ATP. Water is produced as a byproduct when oxygen accepts electrons and protons.
