Bicameralism is adopted because it

Bicameralism is a system of government where legislative powers are vested in two separate chambers or houses. This system is adopted to prevent arbitrary law making and ensure checks and balances within the legislative arm of government. The two chambers have different compositions, functions, and terms of office, which helps to ensure that laws are properly scrutinized, debated and reviewed before they are passed. This helps to ensure that no single group or individual has too much power or influence, and that the interests of different sections of society are represented. In summary, bicameralism is adopted to ensure a more effective and accountable system of government.
