Was chalk once living material
The process by which energy from sunlight is used to transform carbon dioxide from the atmosphere into the organic matter that fuels food webs. The process by which living organisms break down organic compounds to produce usable energy, releasing carbon dioxide into the atmosphere as a by-product. The complex flow of carbon between …7 Pigments (dry, natural, colored materials) are mixed in with the calcium carbonate while both are dry (the procedure is similar to sifting flour and baking powder together before adding liquid, as in a cake recipe). Water is then added to the mixture, which is then baked in the same manner as white classroom chalk.
