When sitting and also watching a fire, that is basic toget the idea the it is alive. The movesdynamically, dancing and also sending sparks. It isable to spread throughout a surface, and move aboutfrom combustible object to combustible object. Itconsumes such materials as wood, convert theminto ash and also other byproducts. It needs oxygen,as despite it were breathing. However, fire ismost definitely not alive.In fact, nobody ofthese criteria prove the something isalive!Oftentimes we think the all liferequires oxygen. However, there are many bacteria(called anaerobic bacteria) which execute not needoxygen at all! castle live down in the soil, underoceans and lakes, and also in various other areas. To plenty of ofthem, oxygen is a poison! yet they room definitelyalive. So plainly whether or not something needsoxygen walk not show if the isalive.Consciousness together we think of that isprobably not a great determinant for life either. It is extremely unlikely the bacteria, fungi,plants, and also other organisms think, since they lacka mind or nerves. However they are absolutely alive. As such whether or not something thinksdoes not display that if is alive. This is the samefor movement, because not all living points move-- in fact, many living things move a lot less thanfire! and many non-living things move, such asthe wind or a car.In order for somethingto be taken into consideration alive that must have severalcharacteristics and abilities, such together metabolism,growth, reproduction, and an answer to stimuli oradaptation to the environment. How does firestack up to these requirements?Firecertainly seems able to grow. A little campfirecan conveniently grow to the level of a forest fire, soyes, it appears to meet this criterion.Canfire reproduce? Again, it seems able to! Asingle spark deserve to blow to a various location andstart a new fire. That could be consideredreproduction!

Answer 2:

Fire is no alive, back it absolutely seems tohave a mind of that own! The process of oxidationis as soon as substances react v the oxygen in theair to do oxides (like rust on iron, is ironoxide, and also when her mom"s silver tarnishes, thatis silver- oxide). When things oxidize, theyrelease heat. Fire is just really rapid oxidation.Heat rises, and also makes currents of air thatcirculate as the hot air rises - that is whyflames show up to dance and also move around. Fire needsoxygen come burn, and it demands fuel; for somethingto "burst into flames" it needs to be in ~ a highenough temperature. Without any type of one the theseingredients the fire won"t burn. A flame onearth is in a gravitational field - the is why itis thicker at the bottom. Yet a flame in the spaceshuttle, in what they speak to "microgravity"(*)environment is actually round! Pretty impressive -imagine a "flame ball"! (* actually there isplenty of heaviness up there - the is why theshuttle stays in orbit - yet it is in a state of"free fall" approximately the planet so girlfriend _feel_weightless.)

Answer 3:

Biologists have battled a little over the basicdefinition of life, yet all biologists would certainly agreethat fire is no alive. Remember, not all livingthings feed on oxygen (plants feed on carbondioxide), for this reason that"s not a good an interpretation forlife. Not all living things move (again, tree donot yes, really move), for this reason that"s no a an extremely gooddefinition of life. No all living points "think",either (plants execute not think).What her questionreally comes down to is just how to define life. I"vetried to come up v some simple definitions oflife. -- because that me, life deserve to be identified by it"smost basic building block -- a cell. If somethingdoes no contain at the very least one cell, it is notalive. Fire does no contain cells. -- Livingthings contain DNA and/or RNA, proteins whichcontain the straightforward information cells usage toreproduce themselves. Fire does not contain DNA orRNA. -- living things space made of matter,and you deserve to weigh them. It might be difficult to measurethe load of one bacteria, however you get the point.You cannot sweet fire, because it is simplyenergy. It has no mass. Fire is energy given offwhen issue burns. You can see it, but what yousee is merely light, so friend cannot hold it. --Living things grow, and also in growing they make newmatter, yet it"s not just any type of old matter. Lifeis organization. Every living points make the samebasic things: proteins, fats and also carbohydrates,for example. Fire cannot make proteins native theoxygen and hydrogen and also carbon the "feeds on", justdestroy proteins. This is a significant difference.-- living things need nutrients andwater, and have complicated ways that finding and usingthe things in their external atmosphere that theyneed. Life things likewise have methods of sensing andresponding to danger or attack.

Answer 4:

That"s a good question since fire does havesome things in usual with life things. The needsfuel and oxygen. It can grow. It "reproduces" tomake more fires. However fire is additionally differentfrom living things. Because that one thing, it is no madeof cells. All living things space made that cells.Also, when fire "reproduces," no informationis happen on. In life things, DNA carriesinformation from one generation to another. Allliving points are adjusted to where and also how theylive through evolution, which transforms DNA over time.Fire is usually the exact same every time. It may bebigger or smaller, hot or less hot, or movingdifferently, however that"s all because of theconditions right now, not because of informationit inherited in DNA.Another distinction is thatall living things come from other living things.One-celled living things divide come make 2 newone-celled things. Eggs, spores, seeds, babies,and growing brand-new individuals from components of their"parents" are all methods to reproduce new life fromlive things. Fire can come indigenous a match, rubbingsticks together, a spark, or various other things that arenot fire.So fire is a great example ofsomething that has some characteristics of life.Thinking around ideas choose this helps united state to reallyfigure out what we typical by life.If friend couldmake robots the made various other robots, would they bealive?

Answer 5:

According come Hickman, Roberts, and also Larson (1997),any life organism will satisfy the complying with sevenbasic nature of life:1) Chemicaluniqueness. Living systems show a uniqueand complicated molecular organization. 2)Complexity and hierarchical organization. Livingsystems show a unique and also complexhierarchical organization. 3) Reproduction.Living systems can reproduce themselves. 4)Possession the a hereditary program. A genetic programprovides fidelity of inheritance. 5)Metabolism. Life organisms preserve themselvesby obtaining nutrient from their environments.6) Development. All organisms pass v acharacteristic life cycle. 7) Environmentalreaction. All animals interact v theirenvironment.Fire is no alive. It does notcontain gene inheritable information, andarguably walk not have actually a facility organization.

Answer 6:

While that is true that fire feeds ~ above oxygen andmoves that is lacking a very important feature to beconsidered alive.
