Answer 1

Explanation:

Multicellular organisms are more efficient in functioning because of division of labour. Different functions of the body such as digestion, circulation etc, are distributed to different cells, so work load is less. But in unicellular organisms, one cell has to do all the functions that are needed for the survival of the organism.
