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.
A resource formed mainly from the remains of microscopic-sized marine organisms buried beneath the ground petroleum. The kind of energy produced when billions of atomic nuclei from uranium are split apart in a fission reaction is nuclear.
Diatomaceous earth and limestone are both sedimentary rocks composed of the remains of ancient organisms. However, they are chemically different. Diatomaceous earth is mainly composed of the silica cell walls of diatoms, while limestone is mainly composed of calcium carbonate from the shells and skeletons of marine organisms.

Kingdom Monera is mainly made up of prokaryotic organisms and kingdom protista is mainly made up of eukaryotic organisms.
The chalk that forms the White Cliffs of Dover is primarily made up of calcium carbonate from the remains of microscopic marine organisms which lived millions of years ago. Over time, these remains accumulated on the sea floor and were compressed into chalk through geological processes. So, the cliffs are mainly formed from fossils.
Prokaryotes are singular celled organisms. Bacteria (mainly)are known as Prokaryotes.
