Cycle of Photosynthesis and Respiration - VTAide

Organic and inorganic carbon reservoirs in Earth's crust are large with long residence times. Carbon enters the geosphere through the biosphere when dead organic matter (such as peat or marine algae) becomes incorporated into fossil fuels like coal and organic-matter-rich oil and gas source rocks, and when shells of calcium carbonate become limestone through the process of sedimentation briefly described above. These carbon reservoirs can remain intact, that is, the carbon can remain stored within them, for many millions of years. Eventually, most rocks are uplifted and subjected to exposure to the atmosphere where they are weathered and eroded, or they are subducted, metamorphosed, and erupted through volcanoes, returning the stored carbon back into the atmosphere, ocean, and biosphere. Our society's dependence on fossil fuels bypasses this natural process by moving as much carbon from the geosphere to the atmosphere in a single year as what might otherwise require hundreds of thousands or millions of years. In Pennsylvania, when we strip mine and burn coal we are in effect releasing the atmospheric carbon dioxide and stored energy of the sun that has been buried for over 300,000,000 years!

Photosynthesis Cycles Flashcards | Quizlet

During the process of photosynthesis, plants take in water, carbon dioxide, and sunlight.

Plants: Photosynthesis and The Carbon Cycle - YouTube

Dark reactions make use of these organic energy molecules (ATP and NADPH). This reaction cycle is also called Calvin Benison Cycle, and it occurs in the stroma. ATP provides the energy while NADPH provides the electrons required to fix the CO2 (carbon dioxide) into carbohydrates.

Amplitude of carbon dioxide diurnal cycle in Biosphere 2 much larger than for free atmosphere (see for example Mauna Loa CO2 record, )

When matter is decomposing, it releases carbon dioxide, which can then be used for photosynthesis.

Tropical Rainforest Carbon Cycle by Rania Nasif on Prezi

Both molecules and carbon dioxide (CO2) are needed in the light independent reaction (Calvin Cycle) to produce a hexose sugar, such as glucose, from RuBP.Glucose is used to in the mitochondrion to produce the energy molecule ATP.

Recall that plants use water, atmospheric carbon dioxide, and energy from the sun to build their organic framework through photosynthesis. Therefore, plants draw down atmospheric carbon dioxide as part of their life habit. When plants die, the organic matter is oxidized and carbon dioxide is returned to the atmosphere.

The carbon cycle is of interest to understanding climate because it includes two of the most important greenhouse gases: carbon dioxide (CO2) and methane (CH4). Most atmospheric carbon is in the form of CO2, while CH4 is present only in trace concentrations. Because CO2 is chemically inert, it is relatively well mixed within the atmosphere away from forest canopies, whereas CH4 is chemically active and is removed quickly from the atmosphere through oxidation to CO2 and water. The overall atmospheric concentration of these greenhouse gases has increased during the past century and contributed to global warming.

Photosynthesis absorbs carbon dioxide (CO2) and converts it into energy as biomass

In subsequent lessons, we will examine and discuss the effects of anthropogenic carbon dioxide emissions and climate change on critical zone processes.

TIM WHITE: I've traveled to Bear Meadows, a national natural landmark, about eight miles southeast of Penn State's main campus in central Pennsylvania. I've brought you here today to describe the relationship between atmospheric carbon dioxide content and organic carbon storage at the surface of the Earth within the critical zone. Let's go have a look at the bog.
