your TEE is your total energy expenditure.

It is the number of calories you burn

in a day and you burn them by:

just being alive, which is your RMR,

Resting metabolic rate is the number of calories you would burn if you were awake but at rest the whole day. This depends on your age, height and weight and whether you're male or female.

doing your daily activities,

A programmer who sits all day at his desk burns less calories than a construction worker who is on his feet all day.

and through exercise.

Someone who runs and trains for races burns more calories than someone who walks his dog everyday, who in turn burns more calories than someone who does not exercise at all.
