BIOLOGY - Environment - Carbon Cycle part 1

The video explains the carbon cycle, highlighting the roles of photosynthesis and respiration in cycling carbon using solar energy. It discusses how plants capture carbon to build material, which animals consume to grow. Respiration returns carbon dioxide to the atmosphere. The video also covers human impact through fossil fuel use and details biological processes like digestion and molecular building, emphasizing energy needs and the role of carbohydrates.
