https://youtu.be/-_FXXKrfDLs Carbon Balance Carbon Balance Life changed atmospheric chemistry: CO2 & O2 Carbon Story Chemistry of the atmosphere has never been stable Photosynthesis creates glucose used to build sugars, fats, proteins, and nucleic acids Cellular respiration of sugars releases stored solar energy The slow carbon cycle involves medium to long-term geochemical processes belonging to the rock cycle Human activity is rapidly changing the concentration atmospheric CO2. Burning fossil fuels results in oxidizing chemically reduced carbon releasing stored solar energy Take-Home
