Explanation:
Research studies results.
Given what we know, we can confirm that as scientists study fossil records, they can learn much about the species, such as the traits and activities of the organisms in question.
<h3>What does each fossil type teach us?</h3>
- Trace fossils such as footprints can teach us about the activities of the organisms.
- Meanwhile, scientists will use body fossils to learn about the specific traits of early organisms.
- Body fossils can at times also provide insight as to the diet of the species.
Therefore, we can confirm that scientists will use body fossils to learn more about the traits and diets of early organisms while using the uncovered trace fossils to track the activities of these organisms.
