By seed
Pieris....can be grown from seed in a cold frame in spring or autumn, greenwood cuttings in early summer or semi ripe cuttings in mid to late summer with bottom heat
It is possible to root cuttings but it is usually done by grafting.
yes
No it is not a live, cuz the flame do not have cells
it gives off a blue flame
potassium (K) produces a blueish purple flame
Clouds produce but they can't reproduce
by explosion
yes
Any and all heat, like flame, is nonliving. A forest fire is flame and is therefore nonliving.
explosive machanism
Lightning strikes are the most common cause of natural forest fires. Forest fires occur naturally to revitalise the forest ecosystem by burning built-up underbrush and dead growth, as well as fertilising the soil with the resulting ash. Seeds and seedlings have an improved chance of uptake in the post-fire environment than in dense overgrowth.
By explosive action/explosion.
I'm guessing that they do reproduce, considering two factors that add to this particular topic. The first way they can considerably reproduce is through us and our actions. Sometimes, if we have a flame on a candle, we use that single flame to produce another for another candle. Technically, it just reproduced another flame but we caused it to happen. Still, the other flame was made from the previous flame. The second way they can "reproduce" is through sparks that venture off from the original flame. If a spark sets something on fire, wouldn't that be basic reproduction? See, the spark came from the flames and from those flames, it made its way onto something flamable and with that, it burned into it and grew into another flame. I don't know what others say, but I'm assuming that that is basic reproduction, so my answer is yes. Flames do reproduce.
Forest fires happen when a tiny spark bursts the whole forest into flame.
make houses
yes
By splitting/explosive method.
yes
