Exploring the Carbon Dioxide Cycle

The video tutorial introduces the concept of carbon and its significance in living organisms. It explains the carbon cycle, detailing how carbon moves from the atmosphere to plants and animals and back. The tutorial also covers carbon storage in soil and oceans, and how human activities like burning fossil fuels and deforestation disrupt the carbon cycle, leading to global warming. The video encourages viewers to help maintain the balance of the carbon cycle.
