David,
It's all a matter of balancing the effects of the controls really.
Increase in throttle speeds up the airflow over the wings, which in turn increases the lift 'power' of the wings, but for even more lift elevators are used to give the aircraft the optimal angle of attack (i.e. pitch up of the wings/airframe) which increases the lift even more.
The throttle is the thing that makes the difference here though, because if the aircraft is then throttled back, that same nose high attitude of the airframe is then making a giant airbrake throught the airflow, which is ideal for landing.
When coming in for a landing, if you just nose down using the elevators, yes you will lose height, but you will also gain a lot of undesirable speed, and so this method is a lot more uncontrolled (runaway). If you nose up to reduce your speed, and juggle it with the right amount of throttle, then that giant airbrake effect will happen (i.e. you will not have enough throttle to climb, but being a little nose high (using the elevators!) the airframe will be resisting the flow of air a little bit more, resulting in slower forward motion).
I hope that helps!
