I am first found in caves, now prolific online; I am a depiction, a drawing, a symbol, or sign. I will convey whichever mood you could wish; or for that matter, a fist, flask, or fish. What am I?

What is in seasons, seconds, centuries and minutes but not in decades, years or days?

Take one out and scratch my head, I am now black but once was red. What am I?

I come in different shapes and sizes.
Parts of me are curved, other parts are straight.
You can put me anywhere you like,
but there is only one right place for me.
What am I?

I’m tall when I’m young, and I’m short when I’m old. What am I?

I am a five-letter word and people eat me. If you remove the first letter I become an energy form. If you remove the first two letters, I am needed to live. Scramble the last three letters and I am a drink. What word am I?

I serve you by expiring
I vanish faster when I am thin
and slower when I am thick
The wind is my energy
What am I?
