Photosynthesis & Respiration

The video explains the carbon cycle, focusing on photosynthesis and respiration. It details how carbon dioxide is absorbed by plants and converted into oxygen and carbohydrates through photosynthesis. Animals obtain carbon by consuming plants or other animals, releasing carbon dioxide back into the environment via respiration. The video also discusses the role of enzymes and chlorophyll in these processes and compares respiration to combustion.
