You plant the exact same seeds in two different pots with the same type of soil. You put one in a closet and one on the windowsill. You water them both of them, but one does not grow. Why?
The one in the windowsill is too hot.
The one in the closet is lonely.
The one in the closet is not getting sunlight in order to make food.
The one in the closet is not getting air.
