Carbon Cycle Worksheet The carbon cycle is a fundamental part of the Earth's ecosystem involving the movement of carbon through living organisms and the environment. Carbon is essential for life, forming the backbone of organic molecules. It exists in various forms such as carbon dioxide (CO2) in the atmosphere, glucose (C6H12O6) in plants, and in fossi fuels. The cycle includes processes like photosynthesis, cellular respiration, decomposition, and combustion. Fill in the Blank:Fill in the blank with the correct words. Word bank: nucleic acids gloro photosynthesis carbon H2O combustion 1. Carbon is found in large molecules necessary for life, such as proteins, carbohydrates ,lipids,and 2. The process of captures CO2 from the atmosphere and converts it into sugar. 3. Decomposers like bacteria and fungi break down dead materials and return to the soil. 4.
