The correct comparison between a fossil and a trace fossil is:
Both fossils and trace fossils are created by organisms from very long ago. However, a fossil is created by the organism itself, and a trace fossil is created by the activity of the organism rather than the organism itself.
Fossils, such as bones or shells, are the preserved remains of an organism, while trace fossils, like footprints or burrows, represent the behaviors or activities of organisms without preserving their physical remains. The statements about heat and pressure are incorrect, as both types of fossils form through processes involving sedimentation and mineralization, not solely by heat and pressure.
