Preserved animal tracks are called fossils.
can someone me with this problem

The correct answer is trace fossils.

Explanation:

The trace fossils signify the physical proof of the life events of the now-extinct species. The trace fossils comprise trails, tracks, feeding marks, burrows, and relaxing marks. It has been observed that there are large number of trace fossils witnessed in comparison to the body fossils, as one species can produce various traces in the form of footprints, however, only one group of bones can turn into a fossil.  

The majority of the trace fossils were produced in the sand or the soft mud close to a lake, pond, beach, or a river. The tracks left by the organisms get briskly covered by sediments. The process of the formation of trace fossils is almost similar to the development of body fossils.  

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.

kelp are large brown algae that live in cool, relatively shallow waters close to the shore. they grow in dense groupings much like a forest on land. these underwater towers of kelp provide food and shelter for thousands of fish, invertebrates, and marine mammal species.
