CARBON CYCLE

»CARBON CYCLE: Carbon is cycled between the atmosphere, land, water & organisms

CARBON CYCLE

CARBON: “C” is an essential component of fats, proteins & carbohydrates

CARBON CYCLE

CO2: Carbon Dioxide(has 2 double bonds)

CARBON CYCLE

» CO2 is used by plants in photosynthesis to produce carbohydrates & O2

» CO2 is released when organisms retrieve the energy stored in carbohydrates during cellular respiration

CARBON CYCLE

Photosynthesis

CARBON CYCLE

Cellular Respiration

CARBON CYCLE

» CARBONATE: Some carbon becomes bones & shells which do not break down easily. These eventually become limestone

CARBON CYCLE

» LIMESTONE: 1 of the largest carbon sinks

CARBON CYCLE

»CARBON SINK: Reservoir for C. Other examples: rainforest & ocean

CARBON CYCLE

»ORGANIC CARBON: (fats, oils & carbohydrates) are released into the soil after organism dies. These form deposits of coal, oil & natural gas & after millions of years & pressurization…are also called FOSSIL FUEL
