Limestone.
Clastic sedimentary rocks, like conglomerate and sandstone.
A rock formed from living organisms is called a biogenic rock or organic rock. These rocks are formed from the accumulation of organic material, such as shells, coral, or plant debris, that undergoes processes like compaction and cementation to become solid rock over time. Examples include limestone, coal, and chalk.
Chalk is a form of limestone, a sedimentary rock.
Coquina is a sedimentary rock fitting that description.
The cemented shells of marine organisms form limestone, which is a type of sedimentary rock. Limestone is predominantly composed of the mineral calcite and can contain fossilized remains of shells and other marine organisms.
organic/biochemical sedimentary rocks are formed of once-living organisms
Clastic sedimentary rocks, like conglomerate and sandstone.

If the layer is of dead plants, it is a compressed layer known as a coal seam.

The answer is organic sedimentary rock.
Chalk is a form of limestone, a sedimentary rock.
the chemical sedimentary rock, rock salt
Coquina is a sedimentary rock fitting that description.
Chemical sedimentary rocks form from dissolved minerals in water, such as limestone made from calcium carbonate. On the other hand, organic sedimentary rocks, like coal or limestone made from the remains of dead organisms, are created from the accumulation and compaction of organic material over time.
