organic/biochemical sedimentary rocks are formed of once-living organisms
There are three original "Dead" Movies: Night of the Living Dead (1968), Dawn of the Dead (1978), and Day of the Dead (1985) all directed by George Romero. George Romero and Tom Savini (the SP-FX guy) colloborated in the remake of Night of the Living Dead (1990), where Savini directed and Romero produced it. Romero had nothing to do with the remake of the Dawn of the Dead (2004). In 2005 he directed Land of the Dead and in 2008 Diary of the Dead. In the 1980's and into the 1990's there was a series called "Return of the Living Dead" which Romero had nothing to do with. Romero is generally considered the Steven Spielberg of the zombie genre so if you want to see a good zombie movie stick with him, especially the first three "Dead" movies. Since Night of the Living Dead is in public domain you can watch it for free without fear of copyright infringement.

Chalk is a sedimentary rock, specifically, a bioclastic limestone, made of the shells of very tiny marine organisms.
Clastic sedimentary rocks are made of broken pieces of preexisting rock that are compacted together. The mineral quartz makes up sixty percent of the clastic sedimentary rocks.
It is said to be a clastic sedimentary rock.

Sedimentary rocks are made out of sediments.
Organic sedimentary rocks are formed from the accumulation of once living things. Coal is an example of a sedimentary rock.
A sedimentary organic rock is living or was once living like a coral. Chemical is chemically made and is usually man cut.
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.

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

Limestone is a sedimentary rock that is often formed from the remains of dead marine organisms such as shells and coral. This type of rock is composed mainly of calcium carbonate.
