Why do each of Earth's elements consist of living creatures except for one?

Question

Earth=mammals

Wind=birds

Water=marine life

Fire=?

Well it is obvious that nothing can survive in fire. But I've often wondered this because it seems kinda awkward that one element would be left void of any form of life

Answer 1

well these arent really acceptable "elements" of earth anymore....you are also speaking in very broad terms, but your point isnt lost on me

Interesting observation

Answer 2

Birds don't "live" in wind.  They use it for flight.  Nothing truely "lives" in wind.  I wuld argue that both wind and wire are void of life forms.
