Is fire a lifeform? Fire moves, grows, consumes, needs oxygen, gives off waste and can "die".
SpaceGuy50 said:Well I'm sure you would agree that fire meets some of the criteria for life, even if it's nonlife.
(Systema Naturæ)NATURALIA sunt corpora cuncta Creatoris manu composita, Tellurem constituentia, In Regna Naturæ tria divisa, quorum limites concurrunt in Zoophytis.
Lapides: corpora congesta, nec viva, nec sentientia.
Vegetabilia: corp. organisata & viva, non sentientia.
Animalia: Corp. organisata & viva, & sentientia, sponteque se moventia.
These are antiquated.alxm said:(Systema Naturæ)
So, nature is divided into three kingdoms.
Rocks - bodies which accumulate, are not alive nor sentient.
Plants - bodies which are organized and alive, but not sentient.
Animals - bodies which are organized, sentient and which may move themselves.

First, a clarification: Presumably, these are not the same "kingdoms" as in the kingdoms of life, since rocks don't belong. Also, there are more than two kingdoms of life - there are about five now - critters that are neither plant nor animal.

Note that "killing a fire" and reigniting it is indistinguishable from just letting it continue.
This generally will distinguish life from non-life. If you kill a rabbit you can't recreate a rabbit just from the materials at hand.

- Stephen HawkingI think computer viruses should count as life. I think it says something about human nature that the only form of life we have created so far is purely destructive. We've created life in our own image.
So if little green men turned up tomorrow and didn't have DNA/RNA they wouldn't be alive?Rade2 said:Life = Self generated action mediated by nucleic acids.
Debatable - it was always a favorite interview question for medics.Andy Resnick said:What about virii?

Life is an ability of matter to... (ummm...) MANIPULATE ITSELF!
symbolipoint said:Does fire have a property of Irritability? That is, can fire react to a stimulus? A long time ago, a biological science authority listed irritability as a property of life. For Fire, irritability may not be enough by itself. Besides, fire seems limited at best in how it might react to any stimulus.
Clever, but I think he means the fire would try moving away from the water. Instead it just dies creates a a barrier from its food.Ukitake Jyuushirou said:I think fire is irritated by water, everytime I pour water on a fire it would hiss in protest...
No, fire is not a living organism. It does not have cells, does not grow or reproduce, and does not require nutrients or energy to survive.
Fire moves and spreads because of a process called combustion. This is when a fuel source combines with oxygen and releases heat and light energy.
No, fire cannot die in the traditional sense. It can be extinguished or run out of fuel, but it does not have the ability to die like living organisms do.
Fire can interact with its surroundings in various ways, such as heating up objects, releasing smoke and gases, and causing physical damage.
Fire is not essential for life, but it does play a crucial role in many ecosystems. It helps with nutrient cycling, plant growth, and can even promote seed germination.
