Coal
Coal is a combustible black rock that is formed from prehistoric plant remains. Coal is formed from the anaerobic decomposition of dead plant matter such as trees, ferns, mosses and other marsh plants that grew on the earth surface over millions of years ago. Coal is composed largely of carbon and is usually burned as a fuel.
Two of the most important energy-carrying molecules are glucose and ATP.
Genetically engineered seed, or GMO, are foods produced from organisms that have had changes introduced into their DNA using the methods of genetic engineering.
