Answer:
I am a food with 5 letters. If you remove the first letter I am a form of energy. Remove two and Iām needed to live. Scramble the last 3 and you can drink me down.
If you drop me, I'm sure to crack. Give me a smile and I'll always smile back. What am I?
I go up, let out a load and then go back down. What am I?
I go up and down at the same time. Up towards to sky and down towards the ground
I lose my head in the morning and regain back it at night.
Whoever made me don't want me. Whoever bought me don't need me. Whoever use me don't know me.
