Can u explain me the law of diminishing marginal utility

Dear Student
Law of Diminishing Marginal Utility states that as a consumer consumes more and more units of a commodity in succession then, the utility derived from the consumption of each additional unit of the commodity falls.

From the schedule and diagram above, we can observe that as more and more units of the commodity are consumed, the Marginal Utility derived from the consumption of each additional unit of the commodity tends to fall. With the consumption of the successive units, the Marginal Utility becomes zero and consequently becomes negative. (As per the schedule, MU is zero at the consumption of 6th unit and becomes negative at 7th unit consumed).
