Carbon Cycle Fluxes and Reservoirs (lawrence hall of science)

Front

FLOW-Animal Respiration

(30 gigatons per year)

carbon and oxygen

Back

Animal Respiration

when animals break donw the food they eat, they breathe out Carbon Dioxide into the atmosphere.

Front

FLOW- Animals Eating (30 gigatons per year)

carbon

Back

Flow- Animals Eating

Animals eat plants and/or other animals. all cells of every plant and animal contain carbon.

Front

FLOW- Atmosphere to ocean (90 gigatons per year)

oxygen and carbon

Back

Atmoshphere to Ocean

Carbon Dioxide from the atmosphere dissolves in ocean water.

Front

FLOW- Ocean to Atmosphere (90 gigatons per year)

oxygen and carbon

Back

Ocean to atmosphere

Carbon dioxide moves out of ocean water and into the atmosphere

Front

FLOW- plant respiration (60 gigatons per year)

oxygen and carbon

Back

Plant respiration

plants need to use of some of their sugars to survive. plants give off carbon dioxide into the atmosphere as they break down their own sugars for life processes. this happens during the day and at night.

Front

FLOW- Natural leakage and breakdown of fossil fuels (.05 gigatons per year)

oxygen and carbon

Back

Natural leakage and breakdown of fossil fuels

small amounts of fossil fuels (natural gas, crude oil, or coal) leak from underground to the surface. at the surface, the fossil fuels naturally break down into carbon dioxide, which flows into the atmosphere.

Front

FLOW- Plant and animal decomposition (30 gigatons per year)

carbon

Back

plant and animal decomposition

after plants and animals die, decomposers break them down into their different nutrients, which enter the soil. this is a way carbon flows into the soil reservoir.

Front

FLOW- Gas from decomposition (30 gigatons per year)

carbon, hydrogen, and oxygen

Back

Gas from decomposition

decomposers, such as bacteria and fungi, give off carbon to the atmosphere as carbon dioxide or methane when they break down carbon from dead animals and plants into their different nutrients.

Front

FLOW- Photosynthesis (120 gigatons per year)

oxygen and carbon

Back

Photosynthesis

land plants take in carbon dioxide from the atmosphere and water from the soil to make sugars.

photosynthetic organisms in the ocean take in dissolved carbon dioxide from the water to make sugars.

Front

FLOW- Volcanic Eruptions (.03 gigatons per year)

oxygen and carbon

Back

Volcanic Eruptions

volcanoes release carbon dioxide into the atmosphere from rocks that are deep in Earth's crust.
