Human needs are considered in hierarchy and often described by Maslow's theory. Here, the concept has been modified and it is observed that additional needs are created once one reaches at higher level of needs, hence additional lower level needs becomes unsatisfied needs and are to be satisfied to satisfy higher order of higher level needs. Motivation depends upon the level and order of needs.
