The energy comes from 2 sources:
Carbohydrates from the bun which are broken down into sugars. These are used for respiration to produce a substance called ATP, which is basically a molecule that carries/releases energy throughout your body.
Fats from the burger/cheese are broken down after your carbohydrate stores are broken down, also producing ATP.
In short, the chemical energy in the burger is used to make ATP which releases the energy in your body as you need it.
Hamburger comes from cow meat. Cows eat grass to live. Grass needs the sun to grow. Therefore hamburger gets its energy from the sun.
It isn't exactly "turned into energy"; grain already HAS energy. When we eat it, we are eating the chemical energy stored in the grain.
It goes from chemical to kinetic.
The only wrong way to eat a hamburger is to not eat it.
no
hamsters don't like when there turned on there back because in the wild when they were turned on there back the next minuet the predator would eat them):
yes.

Yes.
No, they do not.
AND boolean
no
