What about (a)   ? This forms in a similar way – organic matter accumulates in a place with little (b)   , is buried, ‘cooked’ and turned into a useful substance and store of energy. Coal forms from (c)   which is plant matter in wet places on land. Oil forms from organic matter that settled on the (d)   to form a substance called (e)   .
