chalk
limestone. A rock made up mainly of the shells or fragments of shells of megascopic (clams, oysters, snails) animals is a coquina. If the rock is composed of the shells (tests) of microscopic plants and animals it may be called chalk. Limestone can be a hardened chemical precipitate of CaCO3 without an organic source, and take many forms: oolite for example.
Clastic: These rocks are composed predominantly of broken pieces of older weathered and eroded rocks Non-clastic/ Organic: A sedimentary rock composed of the remains of plants and animals.

Soil is made up of a mixture of decayed organic material, living organisms, and minerals. The organic materials come from dead plants like banana peels and last year's leaves. The living organisms range in size from moles to microscopic bacteria. The minerals come from the rocks underground, which are classified as bedrock. Soil is made up of many layers. This is because plants grow on top of the soil and rocks are found underground. The type of soil that forms in a region will depend upon the climate, the bedrock underground, or the plants growing there. Although all soils are made of these basic ingredients, there are many variations. In forests for example, the soil may be deep, rich, and may have a dark brown color. In sandy areas the soil will be dry with a dusty gray color. In tropical regions the soil is often very deep and bright red.

"Phytoplankton" refers specifically to microscopic plant-like organisms that live in aquatic environments and photosynthesize to produce energy. "Plankton" is a general term that encompasses a wider range of organisms, including phytoplankton, zooplankton (animal-like organisms), and bacterioplankton (bacterial organisms). Phytoplankton are a subset of plankton.
Limestone and chalk.

Limestone made from shells would be an organic sedimentary rock.
An organic sedimentary rock composed of cemented shells is called limestone. Limestone is primarily made up of the mineral calcite, which is derived from the shells of marine organisms like coral and mollusks. Over time, these shells accumulate and compress to form solid rock.
Limestone is a type of stone made up of microscopic particles of shells that have been cemented together. This sedimentary rock is formed over millions of years as the shells accumulate and compress into solid rock.
Any Type Of Limestone
The class of sedimentary rocks made of fragments of rock minerals and shells is known as clastic sedimentary rocks. These rocks form from the accumulation and lithification of sediments such as sand, silt, clay, and sometimes organic material. Examples include sandstone, shale, and conglomerate.
Limestone is a chemical sedimentary rock formed from the precipitation of calcium carbonate. It is primarily composed of mineral calcite, which is organic in origin but can also form through inorganic processes. So, limestone is considered both a chemical and organic sedimentary rock.
This type of sedimentary rock is called organic sedimentary rock. It forms from the accumulation and compaction of plant and animal remains, such as shells, skeletons, and plant materials. Common examples include limestone, coal, and chalk.
Organic sedimentary rocks are made up of once living organisms. Examples include limestone, chalk, and coal, which form from the accumulation and compaction of organic remains like shells, coral, and plant material. These rocks preserve clues about ancient environments and life forms.
The answer is organic sedimentary rock.
Organic sedimentary rocks are formed from the accumulation of once living things. Coal is an example of a sedimentary rock.
