Answer:
I am owned by the poor, the rich do not need me. If you eat me, you will die! What am I?
I can fall off a building and live but in water I will die.
I only exist when you are here. Where you never were I can never be.
I am known for my natural tuxedo and marching. What am I?
You throw away my outside you cook my inside. Then you eat my outside and you throw away my inside.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
