Answer:
Unicellular organisms are one cell and have a simple body structure All the functions are made by that one cell. Multicellular organisms are multiple cells and have a complex structure.
They utilize what they have but both are efficient its just that eukaryotic organisms have a better system for surivival and storage than prokaryotic which in contrast needs a lot of sustained energy. Both produce energy and expel waste. Both of them need oxygen, food, water amino acids, and a way to leave waste, but that depends on the type of cell to survive.
Unicellular organisms are made up of only one cell that carries out all of the functions needed by the organism, while multicellular organisms use many different cells to function.
