Answer:
The President of the United States is in charge of the executive branch of the nation, with the task of administering its resources and controlling compliance with the laws that govern the country.
For its part, Congress is the holder of the legislative power, and as its name indicates, it is in charge of legislating, that is, enacting laws and regulations that govern life in society and regulate the government.
Finally, the Supreme Court is the head of the judiciary, in charge of punishing those who violate the laws of Congress, and determining their validity.
In turn, they all control each other through the checks and balances system, avoiding the development of tyrannies. For this last reason, the three are equally important for the democracy of America, although the President of the United States is the one who has a more consolidated power in front of society.
