Final answer:
The Entry ID is the unique identifier that tracks the order of task and resource entries in project management, differing from Task ID and Project ID.
Step-by-step explanation:
The unique identifier that tracks the order in which you enter tasks and resources in a project management tool is known as the Entry ID. This identifier is different from the Task ID, which is often a number that uniquely identifies a task within a list or database, or the Project ID, which identifies a whole project. The Entry ID helps to preserve the original entry order and allows the project manager to view the tasks in the sequence they were added.
