For every action there is an equal and opposite reaction.
The energy acquired by the ball falling is exactly what makes it bounce. It does this until all energy is spent.

A ball with gravitational potential energy is dropped from a height. During its descent, the potential energy of the ball is constantly being converted to kinetic energy. Just before it hits the ground, the ball has all kinetic and no potential energy. The amount of kinetic energy of the ball compresses the ball as it comes into contact with the ground, and this leads to an increase in pressure inside the ball. In order to equalise this pressure instability, the ball tries to regain its original shape, and in doing so, uncompresses the compressed portion, and as a result the ball "bounces" back up.

When the ball is dropped from a height... it has lost potential energy which is converted to kinetic energy...When the ball hits the ground....kinetic energy is converted to elastic potential energy stored in the form of deformation in the ball...which is converted back again to kinetic energy when the ball exerts the same force that the ground exerted on hitting the ground ( newton's third law of motion). And the ball bounces back up.

it is due to its elastisity and when u drope a ball the portion thouching the ground get dipressed by the folling force then the elastisity oercome that force then it regains th depressed portion in to normal shape then it bounce off the ground and the process continues ,...........

Newton's third law, conservation of momentum, and conservation of energy all play a role here.
