Answer:
I believe it goes in the following order: Nucleus, Cell, Tissue, Organ, Organism.
Step-by-step explanation:
I believe it is in this order because cells form to make tissues, so that would mean that the Nucleus and the Cells are smaller than the Tissue. The nucleus is inside of a cell, so that's obviously below the cell. While, organs are within organisms, so that makes the organ smaller than the organism.
