Let’s takes a little time to look at your clothes and think what’s creating it. If you think carbon is the things that create your clothes, you are on the right track. Carbon is an element that stayed in group 14 and period 2. It is the element of life, that all matters are made of carbon. Also, it is everywhere on earth. That’s the reason why in Stem class round 3 we are learning about the carbon cycle. The carbon cycle is the process in which carbon dioxide rise up to the atmosphere by respiration and returning carbon dioxide into living tissues. Carbon cycle has 4 processes which are photosynthesis, decomposition, combustion, and respiration.
Photosynthesis is when the living organism incorporates trees absorb the carbon dioxide and create them into food for themselves.
Respiration is when the living organisms including human and animals inhale the oxygen and exhale as carbon dioxide that goes to the atmosphere.
Combustion is coming from human activity every day that burn fossil fuel and creating the gas into the atmosphere. The gas is carbon dioxide.
Decomposition is when the decomposer breaks down the dead organism and returning the carbon dioxide into the atmosphere from the body by respiration.
Carbon cycle needs to have these 4 processes. If one of those part extinct there will be too much carbon in the atmosphere that will cause global warming.
