Anything can be classified into either a living, non-living, dead, or dormant categories. Plants and animals are living, but animals and human are the first things that humans identify as living. Many people confuse dead with nonliving. Anything dead was formerly living, and anything nonliving was never alive at any point during time. Many objects appear to be in an "in between" category, but everything belongs to a specific category.
Fire is one object that people believe is living, but in fact it is nonliving. In order for something to be a living object, it must have eight qualities. They are: they must exchange gas, they require water, they must grow, they must reproduce, they must eliminate waste, they must contain cells, they must adapt to the environment, and they must use food for energy. They must meet all of these qualities, or be placed in the proper environment to meet these requirements (dormant) to be classified into the living category.
Fire meets a few of these qualities, but for anything to be living it must exhibit all eight characteristics of life. Fire exchanges gases, it intakes oxygen and releases carbon monoxide. Fire can grow, and it also uses food for fuel. Fire exhibits these qualities, but no others. Fire will be extinguished if it were given water; fire contains no cells, and doesn't reproduce. Fire won't adapt to the environment or eliminate waste.
Obviously, fire doesn't meet all of these qualities so it is nonliving. Fire isn't dead because it was never living and fire isn't dormant because it wouldn't be living if placed in any other environments. Therefore, that fire is a nonliving object. .
