The Carbon Cycle

 A carbon cycle is a cycle which shows how carbon circulates through living (biotic) and non- living (abiotic) systems which occurs in the ecosphere. Most carbon are locked up/ fixed into a solid form as sedimentary rocks and fossil fuels (limestone and coal) and the four main carbon storage include:

·         Soil

·         Living things (biomass)

·         Ocean

·         Atmosphere (carbon dioxide)

The carbons are exchanged and moved around randomly through each process as shown in the diagram below:

Living creatures such as human, plants and other animals go through the process of respiration and photosynthesis to exchange carbon (dioxide) with the atmosphere. Therefore carbon is really important to us and other organisms to complete the process of breathing.

The game today had shown that the process in which carbon moves is really random which means it may exchange from the deep ocean into the atmosphere or into fossil fuels or can just stay there forever in the deep ocean. In my case, in the “pre 1700” I was moving more between the atmosphere and the surface ocean than “post 1700” which I only stayed within the deep ocean and the marine life (only in the ocean). The process in which the carbon goes into the atmosphere from the ocean surface is due to evaporation.
