I hide within the food you eat, I give your body strength and heat. Burn me up, and I am gone, Count me daily from dusk till dawn. Too many stored, too few can tire, I’m energy measured, not desire. What am I?

I wear a smile, I wear a frown, I lift you up or bring you down. Though lips may guard what hearts conceal, my every glance can still reveal.

Two caves where the wind can come and go!! People will lie, but pick me to get a tasty treat inside

After much debate over who came first, I'm pretty much over it. I'm what comes out of a chickens bottom, and I'm not talkin s h i t!

Leather skin, but not alive. I help the rider stay and thrive. On trails and tracks I take a dive. What am I?
