To capture the dynamic aspect of a system.

Detailed explanation-1: -It captures the dynamic behavior of the system. Other four diagrams are used to show the message flow from one object to another but activity diagram is used to show message flow from one activity to another.
Detailed explanation-2: -Explanation: Activity diagrams are graphical representations of workflows of step wise activities and actions with support for choice, iteration and concurrency.
Detailed explanation-3: -In UML, the activity diagram is used to demonstrate the flow of control within the system rather than the implementation. It models the concurrent and sequential activities. The activity diagram helps in envisioning the workflow from one activity to another.
Detailed explanation-4: -A behavior diagram is intended to provide clarity, for example, about internal processes, business processes or the interaction of different systems. Depending on the diagram used, a selected aspect is shown. In the Unified Modeling Language (UML), objects are modeled that can change their states through behavior.
Detailed explanation-5: -Purpose of Use Case Diagrams Use case diagrams are used to gather the requirements of a system including internal and external influences. These requirements are mostly design requirements. Hence, when a system is analyzed to gather its functionalities, use cases are prepared and actors are identified.
