olga55 [171]

I wrote a paragraph summing the importance of Carbon a while back, see if it helps find your answer. :)

Carbon is an element on the periodic table with the symbol C, and the atomic number 6. There are many reasons that carbon is vital to life on earth, not only to humans but to plants as well. First of all, humans are made of eighteen percent carbon. It is not only found in humans, it is also found in every organism currently known, including plants in a technological way. To plants, carbon flows inside of their cells. They need it to create glucose which then works as food. To humans, it's used in many science sets. It is used in a vast array of compounds including gasoline. Gasoline is what keeps motors around the world running, and it's made up of hydrocarbons with at least 5 carbon atoms each. It also aids the greenhouse effect, keeping the earth warm and habitable by human beings.
