Answer» Energy conservation statement : Total mechanical energy of an isolated particle or SYSTEM of particles is always CONSERVED in the absence of any dissipative force. As the statement SAYS , the body we are dealing with should be isolated but here the body is not isolated . So to make an increase in potential energy of the system , the lifter has to do some amount of WORK against AIR resistance and gravity . This work done against dissipative force is equal to the increase in potential energy and hence conserving the energy.Explanation:
