Carbon Cycle
Carbon CycleThe carbon cycle is a
biogeochemical cycle in which carbon is cycled throughout the earth.
Carbon cycles throughout plants, animals and the atmosphere in 4 steps.
Steps in the Carbon CyclePhotosynthesisCellular RespirationDecompositionCombustion
PhotosynthesisThe process of
autotrophs taking in sunlight, carbon dioxide and water and converting it into glucose and oxygen.
Cellular RespirationThe process of
organisms taking glucose (C6H12O6) and oxygen (O2) and converting it into energy needed to carry our life processes.
Exs. Mitosis, active transport, running, thinking, eating, meiosis.
Decompositionprocess by which
tissues of a dead organism break down into simpler forms of matter.
Returns carbon to the soil.
Combustiona chemical reaction
producing noticeable light and heat.
Carbon dioxide (CO2) is a product of combustion.
