Final answer:
The political party that holds fewer seats in the senate than any other party is known as the minority party.
Step-by-step explanation:
The political party that holds fewer seats in the senate than any other party is known as the minority party. In a democracy, the minority party plays an important legislative role by offering an alternative viewpoint and voting against legislation they disapprove of, even if it is likely to pass.
They present their ideas in debates and contribute to the diversity of political ideas within the legislature. The minority party can also work with other parties to form a coalition government in situations where no party wins a majority of seats.
