Carbon moves among different systems through the carbon cycle, which includes processes such as photosynthesis, respiration, decomposition, and combustion.
1. Photosynthesis: Plants take in carbon dioxide from the atmosphere and convert it into organic molecules through photosynthesis. This process helps to store carbon in the biomass of plants.
2. Respiration: Organisms, including plants, animals, and microorganisms, release carbon dioxide into the atmosphere through respiration. This process involves breaking down organic molecules to release energy for metabolic activities.
3. Decomposition: When plants and animals die, their organic matter is broken down by decomposers such as fungi and bacteria. During this process, carbon is released back into the atmosphere as carbon dioxide or methane.
4. Combustion: When organic matter such as fossil fuels, wood, or vegetation is burned, carbon is released into the atmosphere as carbon dioxide. This process contributes to the increase in greenhouse gases in the atmosphere.
5. Ocean uptake: The oceans also play a significant role in the carbon cycle by absorbing carbon dioxide from the atmosphere. This helps to regulate the balance of carbon in the atmosphere.
Overall, carbon moves among systems in the form of carbon dioxide, organic molecules, and biomass, affecting the Earth's climate and ecosystems.
