Question

carbon dioxide is present to the extent of only 0.03% by volume in air. Why then is it considered to be so important?

Answer 1

carbon is the most important element because all of the things that we use in our daily life are mainly comprised of carbon for example if we take coal is 90% carbon in coal. Inour body the molecules or I would say the proteins are also made up of carbons the carbohydrates are also made up of carbon but it is not in abundance but still it is necessary for life in earth.
