What is the First stage of the Carbon Cycle?
Carbon enters the atmosphere as carbon dioxide from respiration and combustion
Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis
Animals feed on plants, passing the carbon compounds along the food chain. Most carbon they consume is exhaled as carbon dioxide during respiration. The animals and plants eventually die
Dead organisms are eaten by decomposers and carbon in their bodies returns to atmosphere as carbon dioxide. Sometimes the plant and animal material can be used as fossil fuel in the future for combustion
What is the Second stage of the Carbon Cycle?
Carbon enters the atmosphere as carbon dioxide from respiration and combustion
Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis
Animals feed on plants, passing the carbon compounds along the food chain. Most carbon they consume is exhaled as carbon dioxide during respiration. The animals and plants eventually die
Dead organisms are eaten by decomposers and carbon in their bodies returns to atmosphere as carbon dioxide. Sometimes the plant and animal material can be used as fossil fuel in the future for combustion
What is the Third stage of the Carbon Cycle?
Carbon enters the atmosphere as carbon dioxide from respiration and combustion
Carbon dioxide is absorbed by producers to make carbohydrates in photosynthesis
Animals feed on plants, passing the carbon compounds along the food chain. Most carbon they consume is exhaled as carbon dioxide during respiration. The animals and plants eventually die
Dead organisms are eaten by decomposers and carbon in their bodies returns to atmosphere as carbon dioxide. Sometimes the plant and animal material can be used as fossil fuel in the future for combustion
What is the Fourth stage of the Carbon Cycle?
