Answer:
Limestone is an example of biochemical sedimentary rock.
Explanation:
Sedimentary rocks are those that have been formed due to the accumulation of sediments over time from other rocks or organic remains. They correspond to 75% of the rocks in the world, being the most abundant.
Sedimentary rocks are generally classified, according to the way in which they are produced, in detritic or clastic, and chemical or non clastic; within the latter, there is a subcategory known as biochemistry.
Chemical sedimentary rocks are those that originate from materials deposited by chemical means, where the crystals are held together by chemical bonds or interwoven into each other. The materials, already dissolved, are transported and concentrated to form minerals that accumulate in aggregares and subsequently are lithified as in detritic rocks, to form a rock. Almost all of these rocks originate from chemical precipitation in extensions of surface water, either by inorganic chemical processes or by the chemical activity of organisms. Rocks formed by the activity of organisms are known as biochemical sedimentary rocks.
A clear example is limestone.
