Symbiotic relationship
Explanation:
An average human body between 20 to 30 year of age with a weight of 74 kg and 170 cm contains about 30 trillion cells. The number of bacterial cells in the same man counts for about 39 trillion that is higher than the cell of the body.
The ratio between the bacterial cell to the human cell is about 1.3:1 which is almost equal or higher than the human cells.
