Final answer:
Federal agencies divide funds according to the spending bill through a process called apportionments. The appropriations process involves legislative decision-making for government spending, with an appropriations bill being the primary legislative means for allocating federal funds.
Step-by-step explanation:
The federal agencies have the authority to divide funds among offices or programs in accordance with the spending bill, and these divisions of funds are called apportionments. The appropriations process is the method by which the legislative branch, which includes a congress, parliament, or assembly, decides how the government's money will be spent amongst various agencies responsible for implementing policy.
An appropriations bill is the legislation that allows the federal government to spend money. It specifies how much money will go to different government programs and services. This process starts with the President, who recommends a budget, but ultimately, the power to allocate funds rests with Congress, who must pass appropriations bills.
