BIOGEO CHEM 25-26

QuestionAnswer
Carbon cycle Movement of carbon through living and nonliving parts of Earth
Carbon is important because It is the basis of all organic molecules
Carbon changes form in the cycle because It exists in different chemical forms
Carbon in the atmosphere is Carbon dioxide (CO₂)
Carbon in plants is stored as Glucose (C₆H₁₂O₆)
Carbon is found in living things as Proteins, carbohydrates, lipids, and nucleic acids
Carbon reservoirs include Atmosphere, oceans, rocks, soil, fossil fuels, living organisms
Photosynthesis is The process plants use to capture CO₂ and make sugar
Photosynthesis removes carbon from The atmosphere
Photosynthesis equation 6CO₂ + 6H₂O
Cellular respiration is The process organisms use to break down sugar for energy
Cellular respiration releases Carbon dioxide into the atmosphere
Cellular respiration equation C₆H₁₂O₆ + 6O₂
Consumption in the carbon cycle is One organism eating another to obtain carbon
Decomposition is The breakdown of dead organisms by decomposers
Decomposers return carbon to The soil and atmosphere
Examples of decomposers Bacteria, fungi, earthworms
Fossilization is The process that forms fossil fuels from dead organisms
Fossil fuels are Coal, oil, and natural gas
Combustion is The burning of fossil fuels or wood
Combustion releases Carbon dioxide into the atmosphere
Animals get carbon by Eating plants or other animals
Plants remove carbon from the air by Photosynthesis
Animals, plants, and fungi release carbon by Cellular respiration
Human activities increase carbon by Burning fossil fuels
Burning fossil fuels causes Increased CO₂ in the atmosphere
Increased atmospheric CO₂ leads to Climate change
Carbon cycle is important because It keeps carbon available for life
