The jumper pushes on the ground. By Newton's third law the ground pushes back on her with the same force. So it is the Earth that forces her up into the air.

well, i believe it is a newtons third low
on exerted force there is awlways oposite side force too. which mean when you push a wall the wall put the same force back to u. that is why when you punch wall it hurts you, because of the force exerted by the wall,
so in the jumper case (i believe) if they have a stick the put a force on ground and the stick and they light thier body (relax) so the opposiet for exert by the the ground and the tick can put them up.
i hope you got me

It comes from the muscular tension between its/her/his legs... The muscular contractions made it possible for a jumper to force itself upward...
