Final answer:
Trace fossils provide valuable information about an organism's behavior and activities.
Step-by-step explanation:
Trace fossils provide a wealth of information about how an organism lived because they give us direct evidence of the organism's behavior and activities. Unlike body fossils, trace fossils show us the actual movements, burrows, tracks, and even excrement left behind by organisms. By studying these trace fossils, scientists can make inferences about the diet, habitat, locomotion, and social behavior of extinct organisms.
