(A) Photosynthesis in land plants fixes atmospheric CO2 (inorganic carbon) as organic carbon, which is either stored as plant biomass or in soil, or is decomposed back to CO2 through plant and ...

November 2024/Kiel. Professor Dr Susanne Neuer, renowned marine biogeochemist and professor at Arizona State University, was awarded the 31st Excellence Professorship from the Prof. Dr Werner Petersen ...

This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

This is followed by topics essential to understanding the carbon cycle, including organic geochemistry ... for my courses in marine cycling of elements for M. Sc. students in biology and for graduate ...

LeafWeb collects data about photosynthetic traits from scientists around the world to support carbon cycle modeling. The scientists verified the model results by comparing them with high ...

If Earth's history were a calendar year, humans would not appear until the last few minutes before midnight on Dec. 31.

In this activity, students simulate a molecule of carbon’s movement through various locations in the carbon cycle, before acting out different human impact scenarios. I have collaborated on ...

Animals feed on plants, passing the carbon compounds along the food chain. Most carbon they consume is exhaled as carbon dioxide during respiration. The animals and plants eventually die.

Diatoms are too small to see with the naked eye, yet they are one of the most productive algae species in the ocean and play an important role in the global carbon cycle. Using photosynthesis ...

Modeling of Southern Ocean carbon and nutrient cycles under present and future climates; understanding how ocean circulation, the cryosphere and biology interact to shape high-latitude biogeochemical ...

Dead organisms are broken down into smaller pieces by the process of decay. Organisms such as earthworms are involved in this process.

as part of what is called ‘the global carbon cycle.’ A change in any of these fluxes could have wide-ranging impacts on ecosystems and our climate. The IAEA Environment Laboratories apply nuclear and ...
