'verlieren' and 'abwerfen' can both mean that something is no longer on a person, animal, or plant. 'verlieren' is general: afterward, you no longer have something. 'abwerfen' is more specific and often describes a natural process, for example when a tree sheds leaves or an animal sheds its antlers. Learners may confuse the words because the result is similar. The difference lies in the perspective: 'verlieren' emphasizes the loss, while 'abwerfen' emphasizes the active or natural process of getting rid of something.

Many trees shed their leaves earlier in dry weather.
