Answer
Failing to manage observer lifecycle properly can lead to memory leaks.
If observers are not properly removed from the subject's list of observers, they can continue to receive updates even after they are no longer needed, leading to memory leaks. For example, if a user interface component is an observer, it should unregister itself when it is no longer displayed.
