Carbon( Processes and Pathways )

• The carbon cycle is the movement of carbon between living organisms, the atmosphere, oceans, soil, rocks, and fossil fuels.
• Carbon dioxide (CO2) is released into the air when plants die or are burned as fuel.
• Photosynthesis converts CO2 to organic matter, which can be used by animals and humans.
• Carbon dioxide (CO2) is released into the air through respiration by plants and animals, as well as from burning fossil fuels like coal, oil, and gas.
• Decomposers break down dead plant and animal material, releasing CO2 back into the environment.
• When an animal dies, its remains decompose back into CO2 through respiration and decay.
• Fossils form from the remains of dead organisms that have been buried under sedimentary rock layers over millions of years.
• Plants absorb CO2 during photosynthesis and release oxygen (O2).
• Animals breathe out CO2 and take in O2.
• When these fuels are burned, they release large amounts of CO2 into the atmosphere.
• Humans have increased the amount of CO2 in the atmosphere through activities such as deforestation, agriculture, and industrial processes.
• The process of decomposition involves breaking down dead plant and animal material, releasing CO2 back into the environment.
• Burning fossil fuels releases large amounts of CO2 into the atmosphere.
• The carbon cycle involves the movement of carbon between living things and their surroundings.
