What kind of motor are you taking about?
If the motor has the capability to produce X amount of force constantly (to a limit), even if the “load” varies, then yes it will consume more energy to push/move a higher load. Just like a car engine, it can achieve x mph but the more weight the car has the more gas it will use to achieve that speed.
Most water pumps in this hobby will produce less GPH the higher the head pressure gets hence reducing the energy consumed.
