What is the relation between UEFI firmware and the EFI system partition?
-2
Since UEFI replaces BIOS, is it also stored in ROM (instead of a disk) as BIOS?
Is it correct that EFI_system_partition in a disk? Is UEFI firmware stored in the EFI system partition? If not, what is the relation between UEFI firmware and the programs stored in the EFI system partition?
Thanks.

The EFI System Partition (ESP) is where the operating system bootloaders live. The EFI firmware knows how to look for a EFI system partition (identified by its GUID,C12A7328-F81F-11D2-BA4B-00A0C93EC93B); the ESP must be formatted with the FAT filesystem, which the EFI firmware understands. The EFI firmware is thus able to load an operating system bootloader from the ESP; the bootloader then executes in the EFI context and is responsible for loading the operating system from disk and giving it control.

In the motherboard firmware, as part of your hardware. Yes, lots of hardware contains software code, including hard-disk, CD recorder, network card, or even CPU.
