see below the dust to dust ashes to ashes referred to there and this if you mean curse of adam and eve is because they ate the apple that was forbidden to them
In reading Genesis 3:17 through :19, Elohim, in speaking to Adam explains what will now happen, because firstly, Adam listened to his wife... but also that the curse for disobeience or betrayal of Elohim's only prohibition in the garden, i.e., eating of the fruit of the knowledge of good and evil, will be that Adam will have to eke out his living by the sweat of his brow... so it appears that all of the above is the most nearly correct answer...
