Sun-provides energy as heat and light
Carbonic acid in

CO2 into

CO2 to air
Carbonic acid
Earth
Organic-made from diatoms(producers) and
skeletons and shells of living organisms
Inorganic made from calcium carbonate
Carbon source refers to all the elements - organic or inorganic, which release carbon in some form
into the atmosphere. Here are the sources: volcanic eruptions; respiration of animals and humans;
decay of dead matter; combustion of fossil fuels; natural processes like conversion of limestone to
lime( releases carbon dioxide), metamorphism of rocks; warm water bodies
Carbon Sinks are anything that absorbs more carbon from the atmosphere than it returns and
include plants, algae, and a few strains of bacteria (photosynthesis ) ; cold water bodies; landfills
(artificial sink)
Carbon Reservoirs store this element in various forms, for small or really long periods of time. They
are: The Earth's atmosphere, which contains copious amount of CO2; organic elements like rocks
(organic limestone); soil ; sediments; limestone and coal deposits; oceans which also contain a lot of
dissolved carbon in various forms as well in the form of fossil fuels; volcanic eruptions and
geothermal activities also release a lot of carbon into the atmosphere.
Biotic: The living or once-living organisms in an ecosystem
Abiotic: nonliving component of an ecosystem
Q 1: Describe the form of carbon in the atmosphere.
Q2: Describe the main sources of carbon on Earth.
Q3: Explain why decomposers are so important to the cycling of carbon around the planet.
Q4: Explain why plants are both consumers and producers of carbon. Refer to respiration and
photosynthesis
PHOTOSYNTHESIS:
RESPIRATION: glucose + oxygen → carbon dioxide + water (+ energy)
Q5: Explain how the environment is affected by humans continuing to burn fossil fuels.
Q6: Coal, natural gas and oil consist mainly of carbon. Explain what a natural reservoir is.
Q7: Identify where carbon moves through the abiotic and biotic components in this cycle.
Q8: What key features make it a cycle? Name the three key components of the carbon cycle. What
powers this cycle?
