Explanation;
-The biological levels of organization of living things arranged from the simplest to most complex are: organelle, cells, tissues, organs, organ systems, organisms, populations, communities, ecosystem, and biosphere.
-Cell is the basic unit and building block of life. It is bound by a cell membrane, and possesses a nucleus which acts as its brain. Arachnoidiscus ehrenbergi is an example of diatoms which are unicellular, therefore it is a cell.

These fossils are very useful for us because we can use them to date the layers of rock that they are found in. Fossils that can be used in this way are called index fossils, and rock layers with the same index fossils in them can be correlated. Not my answer, link here for full

Answer:
the rock breaks down and goes through the 5 step process to become a sedimentary rock again.
Explanation:
1) Weathering (making the sediment by breaking down or dissolving preexisting rocks or living organisms)
2) Erosion (picking up the sediment by water, wind, or glaciers)
3) Transportation (moving the sediment by water, wind, or glaciers)
4) Deposition (depositing the sediment)
5) Lithification (turning the sediment to rock).
