Because it take someone who is 5' 6" and a fat 200 pounds considerably more effort and work to run one mile than someone who is 6' 2" and an athletic 200 pounds to run that mile. Men and women burn calories differently. Young people burn calories much better than old people.

Yes.

The way I think about it is, if your body didn't get more efficient (or, at some point just shut down your ability to burn fat stores for safety purposes), we could all do one week's worth of work on an exact diet, measure the percentage of fat lost and how many calories were taken in, and then figure out exactly when we could reach a specified goal. Obviously that doesn't work. People plateau and at a certain point, stop losing fat stores altogether. You have to work much much harder to lose the same amount of fat the closer you get to 0% body fat.

Here's an article that looks at the opposite way--reducing muscle efficiency increased calories burned.
