I think it's not the body system you're asking for but our living tissue bone tendon organ muscle brain etc body parts where each type of body part has their own specific & unique type of living cells. Each type of cell does a different type of job. All of these different types of cells making up the different body parts etc all work together as one whole system that makes it possible for us 2 live breathe think etc. But all of the different types of cells work either the same or a similar way. The anatomy of all the different types of cells have the same or similar anatomy. You should look it up because I have a information/data hoarding problem and am a memoryholic. I really don't want to search the web right now.. Cell Anatomy. Mitochondria inside the cell are the things that extract store and use the energy which is broken up 2 be small enough 2 use after going through the digestive system, being absorbed by villa in the small intestine carried through the blood stream and distributed to all the body parts living cells etc that need the energy to survive.

how much energy the food molecules have
Your body gets energy from what you eat and drink.
Feed = food I'm guessing... It is digested in the same way as humans do - the digestive system extracts the vitamins and minerals from the food and then the unwanted waste gets... well, you know.
