The given blank can be filled with dinosaur footprints.  

In the Precambrian, the sedimentary rocks deposition took place in the Blue Ridge Province of Virginia, however, no fossils have been positively determined from these deposits. The Paleozoic rocks are well documented in Virginia. The occurrences of shallow area deposition were obstructed by subsequent periods of erosion and mountain-building incidents.  

The withdrawal of the widespread shallow regions of the Paleozoic left much of the state exposed at the time of Mesozoic and Permian. In central Virginia, fossils of freshwater fish, dinosaur footprints, and insects are found in the rift basin deposits of the Triassic.

At one time, biologists thought that fungi were merely forms of plants that had lost their chlorophyll and had returned to sapro
Drupady [299]

Answer & explanation:

Fungi have long been regarded as organisms that were part of the <em>Plantae</em> kingdom (plants), mainly because they have cell walls in their cells, reproduce by spores, and the fact that some of them are sessile (attached to the ground).

However, fungi are no longer considered as plants because they do not have chlorophyll or specialized cells, such as chloroplasts and vacuoles. In addition, fungi have heterotrophic nutrition (plants are autotrophic), needing to absorb organic substances to survive.

Nowadays, fungi are studied in isolation and are inserted in their own kingdom, the <em>Fungi</em> kingdom.

Pachacha [2.7K]
The correct answer is bacteria. Bacteria abundant in soil is the main source of its organic matter. This is because bacteria release energy in their systems which causes the soil to be more fertile and more capable of sustaining plant material. Without bacteria general processes of soil formation will not be possible.
