What energy transformations occur as energy moves from M to N to O and then to Q?

• Light energy from sunlight is transformed into electrical energy at M, which is then transformed into light energy in the lamp at Q.

• Light energy from sunlight is transformed into chemical energy at M, which is then transformed into electrical energy in the lamp at Q.

• Chemical energy from sunlight is transformed into electrical energy at M, which is then transferred into light energy in the lamp at Q.

• Mechanical energy from sunlight is transformed into chemical energy at M, which is then transformed into electrical energy in the lamp at Q.
