The Carbon Cycle
Transcript of The Carbon Cycle
explanation of the carbon cycle
and I hope you had enjoyed it. Then all the cycle starts again. The cycle starts by a process made from the biotic matters in an environment called photosynthesis the process starts with the sun (the beginning of all the cycles and the power source of it). In photosynthesis plants absorb carbon dioxide and they convert it into glucose which they use for feeding themselves and releasing the oxygen we breathe. Plants release this carbon dioxide into the soil (as a waste product) when they use their stored glucose. This process receives the name of respiration. The same thing happens with animals, they eat the carbon contained in other animals or in plants and they also release this carbon dioxide as a waste product by the respiration. Carbon Cycle
Explaination: Decomposers which live in the soil, release all the carbon stored in animals and plants tissues by decomposing them and all this carbon goes back into the atmosphere. Also another part of the cycle interacts with the ocean. Carbon enters the sea water by a process called diffusion and over millions of years it creates shells made from the remains of sea plants and animals, limestone formed from fead marine organisms and later, a sedimentary rock. Also when volcanoes explode, carbon dioxide is released. Another way of releasing the carbon dioxide back into the atmosphere is by burning fossil fuels (remains of plants and animals over millions of years) in special factories. This carbon escapes from the remains while burning them and they go back into the atmosphere. VIDEO TIME Please click play to enjoy a through understanding on the carbon cycle. Importance of the carbon! Importance of the carbon! The carbon cycle is important for life and for us because: Photosynthesis: Oxygen: Fossil Fuels: Essential for life: The carbon cycle is important for life and for us because it helps to make the photosynthesis process and the photosynthesis is very important for us because from this process we get carbon dioxide and oxygen. By the photosynthesis we get all the oxygen we need to breath each day. From this cycle and from photosynthesis we live and survive on earth. When we burn fossil fuels such as coal, oil and natural gas (which we get from the carbon cycle) we use these products for electricity and if we wouldn’t have this cycle, we couldn’t have all the things which make our lifes easier. The carbon is very important because it feeds our cells and this material is in everything we possibly know and without carbon we wouldn’t exist. Every living thing needs carbon to work and our body is 50% made from carbon. We are positively affecting the cycle by planting more plants that make the carbon dioxide we need. Also people are conserving and protecting forests and they are also planting lots of plants and trees to help the carbon cycle to work. This makes the cycle work properly and that it can be balanced in each part of it. Also we affect it because when we breathe and do things for our daily life, we release lots of carbon dioxide and we make that the cycle continues working. 350 is an international group that is bulding a movement against climate crisis. This campaign helps the increase of carbon dioxide. This have to do a lot with the carbon cycle because this cycle releases lots of co2 by burning fossil fuels and by deforestation. This is a video which explains what this group is about: Also there are different groups which help decreasing problems from this cycle and this is another way of possitively affecting it. Also this groups are a way of socially interacting with the cycle. & Deforestation Burning fossil fuels Excess of respiration
& decomposition We are negatively affecting the carbon cycle by deforestation because when we cut tress, less plants can do photosynthesis and we unbalance the cycle. Also we affect it by burning fossil fuels because we are burning and abusing of the fossil fuels and we also un balance the cycle because we need to have the same quantity of carbon in each part of the cycle. Also this activity increases the amount of CO2 and causes the enhanced greenhouse effect which is changing and affecting the world climate. It has changes the temperature and availability of water. Causes ice cap and glaciers to melt, sea levels to rise and distrup ecosystem. Also it isn’t good for the cycle that we have so many respiration and decomposition because there will be a lot of carbon on one part of the cycle and it all needs to be balanced.
The natural processes which help to remove the concentration of carbon in the atmosphere are the sedimentation and the ocean uptake but these processes are very slow. This is a UK government group which helps reduce the outcome of carbon dioxide and global warming.This group is a way of politically interacting with this cycle. This is a graph showing the
increase of CO2 concentration. the concentraion of carbon dioxide in the atmosphere is higher than it has been for the past 800 000 years. This is an image which shows the principal
factors which negatively affect this cycle. This is a graph which shows how much CO2 do deforestation and burning of fossil fuels release. I hope you had enjoyed my presentation
and learned a lot about the carbon cycle!
