Answer:
What is lighter than what it is made of?
My first is in fish but no in snail. My second is in rabbit but no in tail. My third is in up but not in down. My fourth is in tiara but not in crown. My fifth is in tree you plainly see. My whole a food for you and me.
When Iām metal or wood, I help you get home. When Iām flesh and Iām blood, In the darkness I roam.
What goes in the water red, and comes out black?
I never was, am always to be. No one ever saw me, nor ever will. And yet I am the confidence of all, To live and breath on this terrestrial ball.
My days are numbered.
