Carbon cycle
List of topics
Introduction
The Carbon Cycle affects all life on Earth. Elemental Carbon is neither created or destroyed, so the recycling of carbon-containing compounds in the environment is essential to the continuation of life.
Describe briefly the process you will address and the significance of soil microorganisms in the process (what functions do they perform?).
Process - key points
Describe the process, using as many sections/subsections as you require. Look at the list of other topics. Which involve processes similar to yours? Create links where relevant.

Key Classes of Microorganisms in the Carbon Cycle
Autotrophs
An important step of the carbon cycle is the fixation of atmospheric CO2 and the subsequent production of organic molecules. Organisms that can convert CO2 into organic molecules are called autotrophs, and include plants, algae, some bacteria, and some archaea. Some bacteria specifically involved in carbon fixation are Cyanobacteria (such as Chroococcus, Nostoc, and Spirulina) and some species of Aquifex,such as Aquifex aeolicus. Cyanobacteria are also important Nitrogen fixers in the Nitrogen cycle including GHG
Saprobes
Another important step in the Carbon Cycle is the decomposition of complex organic matter to produce CO2 (essentially the reverse of carbon fixation). Organisms important in decomposition are bacteria (such as Streptomycesand Clostridium thermocellum), fungi of all kinds, and protists such as Paramecium.
Identify and describe some microorganisms involved. Do they already have their own microbewiki pages? Add links. Create at least one page for a microbe relevant to your topic. Template will appear soon.
