it’s in the atmosphere, where it helps regulate the

The carbon cycle

Carbon is one of the most abundant elements in the universe and here on earth it is always on the move, just like water, jumping from a reservoir (can be natural or artificial lakes or ponds created to store water) to the next. It can be found almost anywhere, and that’s a good thing because all living things require carbon for their structure and to fuel their bodies. It’s a big component in a bunch of non-living things as well: it’s in rocks, in the ocean, trapped in ice. Plus it’s in the atmosphere, where it helps regulate the temperature. Without carbon dioxide Earth would basically be a frozen wasteland. If we were to take all of the water out of our body, carbon would constitute about half of what remained of us, of our body. It is important for many reasons, first of all it provides us lots of the power that we use. It’s found in coal, in fossil fuels, in all of our main sources of energy. We can find it in many different types of source poles, there’s a lot of carbon in the ocean for example, which is one of our main carbon pools in the planet , we can find it in the atmosphere as different gases, such as carbon dioxide, plus you can find lots of carbon in the terrestrial area, in plants, in trees…

The carbon cycle is the cycle of where carbon goes, so how it moves from one pool to a different one. It is a system, an earth process that transfers carbon from the plant material to the atmosphere, back to the plant material, from the oceans to the atmosphere, back to the ocean and from far below ground from fossilized carbon pools to the atmosphere. Fast moving carbon for example is what gets stored in plants. Plants absorb a bunch of carbon dioxide out of the atmosphere because they need it to photosynthesize (it is a process used by plants and organisms to convert light energy into chemical energy that can later be released to fuel the organisms’ activities). But CO2 is also one of the by-products of respiration, the process by which they use that energy. So plants take in carbon dioxide from the atmosphere during photosynthesis and then release CO2 back out into the atmosphere during the respiration process to make ATP (it stands for “Adenosine Triphosphate” and it is the primate energy carrier in all living organisms on earth) for all their cellular functions. Plants take in more CO2 from the atmosphere than they give off through respiration, the rest is like their profit, it’s what becomes the body of the plant.

Slow carbon will refer to carbon reservoirs in the ocean. Now carbon dioxide dissolves really easily in water, and once it’s in there all of it is used by phytoplankton (tiny plantlike organisms that form the base for the marine food chain). They use it to do photosynthesis and they also use it to form calcium (calsium) carbonate shells. When they die, their shells settle to the bottom of the ocean, pile up, become compressed and over time, make rocks like limestone and, once limestone deposits are eroded by water, the calcium carbonate is broken down to eventually form among other things, carbon dioxide and carbonic acid. We make lime and cement by heating limestone, which produces a pretty good amount of carbon dioxide and when we do burn fossil fuels such as coal and petroleum products and natural gases it also releases carbon in the form of carbon dioxide that’s been stored for hundreds of millions of years in the geosphere.

Climate change and warming This process is what started the atmosphere carbon dioxide rising like crazy in the past couple of hundred years. The excess of carbon in the atmosphere causes global climate change because CO2 in the atmosphere causes some of the sun’s energy from re- radiating back out into space. So our planet has been getting warmer because we’ve been burning through reservoir of carbon that we had locked underground. This is causing all kinds of problems that we can already see and the situation could be helped a lot if we could just stop unlocking all of that carbon and spitting it into the atmosphere, but in some respects we don’t even have control over the situation any more, because of ice, since carbon is often trapped in it. In places like Siberia, Northern Canada and Alaska, cold places that also have plants, they contain huge carbon reserves that are trapped in permafrost (ground that’s frozen year- round). These places are basically wetlands that add another layer of dead plant matter each year. But as permafrost melts, these dead plants decompose and huge amounts of carbon dioxide and methane are released into the atmosphere, creating a positive feedback loop.
