<span>I am a Carbon atom and I took birth in the air. I had spend a memorable time in a molecule and there were two very nice oxygen atoms too. I just got into the air and I am very excited that I had my complete incoming box of electrons. I am a carbon atom and I have six electrons. Right now I am in a carbon dioxide molecule and I am just wondering in air. While i was enjoying my journey I waved to my friends like oxygen gas which is a molecule of two oxygen atoms.Oxygen atom is my best friend. I’ve heard stories of becoming solids and many different things when i was too young, but now I just like the air and I am loving it.</span>
I am carbon atom denoted by a symbol C and my atomic number is 6. I am the member of group 14 in the periodic table. I am tetravalent having 4 electrons to form covalent chemical bond with other atoms. I live in air along with two molecules of oxygen as carbon dioxide(CO₂).
Fixation: algea and terrestrial green plants take me as carbon dioxide from the external environment and convert me into polysacchride as their food in the process of photosynthesis.
Respiration: the consumers obtain the food prepared by the plants and obtain energy from it and again release me in the form of carbon dioxide.
Decomposition: in the decomposition process the animal, plant and human dead and decaying waste is converted from highly complex molecules to less complex molecules, i get produced along with two oxygen molecules (CO₂) in this process.
Fossil fuels: burning of fossil fuels like coal and petroleum leads to again my release as CO₂.
They speed up chemical reactions. Without them you wouldn't be alive. They break down macromolecules, and also lower the amount of energy needed for a chemical reaction to happen.
The major difference is that plants use vacuoles to store excess amounts of water, while animal cells do not. A plant standing up straight compared to a plant wilting over is a result of water capacity in the vacuoles
