AP Environmental Science Unit 1.4: The Carbon Cycle

Pathways

________: Processes that move the elements between the reservoirs.

Deposition

________: The laying down of sediment carried by wind, flowing water, the sea or ice.

Combustion

________: Occurs when any organic material is reacted (burned) in the presence of oxygen to give off the products of carbon dioxide, water, and energy.

Biomass

________: Renewable energy that comes from organic matter /organisms.

Fewer trees plants

________ mean less photosynthesis and glucose.

Fossil Fuel Formation

________: Dead organic matter builds up underground faster than it can be anaerobically decomposed, and sediment pressurizes it.

Photosynthesis

________: The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar.

Cellular Respiration

________: The process of breakdown of food in cells and organisms with the release of energy.

Biosphere

________: The part of Earths surface where life exists.

Reservoirs

________: Places where elements are stored for part of the time.

Diffusion

________: Molecules moving from an area of higher concentration to one of lower concentration.

Ocean Biosphere

________: The part of the Ocean where life exists.

Shell Formation

________: To build shells, marine life extracts calcium and carbonate ions from ocean water, combining them to make shells.

Biogeochemical Cycles

Cycles of elements as they move through living and nonliving factors

Reservoirs

Places where elements are stored for part of the time

Pathways

Processes that move the elements between the reservoirs

Biomass

Renewable energy that comes from organic matter/organisms

Organic Compounds

Compounds that have carbon-carbon or carbon-hydrogen bonds

Photosynthesis

The process by which plants use sunlight, water, and carbon dioxide to create oxygen and energy in the form of sugar

Cellular Respiration

The process of breakdown of food in cells and organisms with the release of energy

Combustion

Occurs when any organic material is reacted (burned) in the presence of oxygen to give off the products of carbon dioxide, water, and energy

Anaerobic Decomposition

Decomposition without the use of oxygen

Fossil Fuel Formation

Dead organic matter builds up underground faster than it can be anaerobically decomposed, and sediment pressurizes it

Diffusion

Molecules moving from an area of higher concentration to one of lower concentration

Shell Formation

To build shells, marine life extracts calcium and carbonate ions from ocean water, combining them to make shells

Deposition

The laying down of sediment carried by wind, flowing water, the sea or ice

Atmosphere

The layers of gases surrounding a planet or other celestial body

Contains Carbon Dioxide (CO2) and Methane (CH4

converts to CO2 and H2O through exposure to Ozone)

Biosphere

The part of Earths surface where life exists

Contains consumers, biomass, and organic molecules (ex

Glucose [C6H12O6])

Lithosphere

The solid, outer part of Earth, including the brittle upper portion of the mantle and the crust

Hydrosphere

All the waters on the Earths surface

Ocean Biosphere

The part of the Ocean where life exists

Contains organisms, biomass, organic molecules (ex

Glucose [C6H12O6]), and Calcium Carbonate

More carbon in the air = more heat

global warming

Traps a lot of heat
