Question

Why energy is absorbed when electron moves from lower orbital to higher orbital?

Answer 1

bcoz to move electron from lower energy level to higher energy level, it need energy that energy it has to absorb from other external source like light ..
other wise its difficult to gor from low energy to high energy unless u take energy from any source :)

Answer 2

This depends on whether the energy level is a greater or lower potential. This can be thought of as imagining standing in the middle of a hill on earth. The higher u go up the hill, the more gravitational energy needed, so energy is required. But u could jump/slide down the hill, thus releasing energy (u'd feel it as kinetic).
When an electron goes down a level, a photon is released, if an electron goes up a level, this is because energy has been absorbed. ..hope u get this ....
