Understanding the Carbon Cycle The carbon cycle is the process through which carbon atoms move through the Earth's atmosphere, biosphere, oceans, and geosphere. It plays a critical role in regulating Earth's climate and supporting life. Key Components of the Carbon Cycle Photosynthesis: Plants and other autotrophs absorb carbon dioxide (CO₂) from the atmosphere to produce glucose and oxygen. Respiration: Organisms release CO₂ back into the atmosphere as a byproduct of breaking down glucose for energy. Decay and Decomposition: Decomposers break down dead organisms, releasing carbon into the soil and atmosphere. Fossil Fuels: Over millions of years, organic matter becomes fossil fuels, which are extracted and burned, releasing stored carbon into the atmosphere. Carbon Sequestration: Some carbon is stored in long-term reservoirs like forests, soil, and ocean sediments. Typical Worksheet Questions and Answer Key What is the primary process that removes CO₂ from the atmosphere?1. Photosynthesis. How do animals contribute to the carbon cycle?
