Diatoms.
uf you don't know so why uyou to go diatoms double shells make of is gul bebe qandol Jan ast this answer is by gulab zo
Limestone is made by the accumulation of shells and marine organisms.
Shells cannot 'decompose' in the biological sense of the word. Only living organisms that have died can be 'decomposed' by 'decomposers'. Shells are made by living organisms but they are themselves non-living objects. They will physically erode, crumble, and be reduced to fine particles, but will remain chemically the same as they started.
Opal is made of silica, but it technically is not a mineral.
Solute silica may be in form of silica gel. Silica is usually made up of silicon which is combined with oxygen.
What they are made of. Calcareous ooze is made from calium carbnate shells of cooclithophores, foraminifera, and other things with carbonate shells. Siliceous ooze is made of silica shells of radiolaria (really cool looking), diatoms, and anything else with a silica shell.
No, it is not flaky . it is calcium carbonate , a sedimentary rock. it's made of shells of animals.

Glass is silica dioxide. It is made by melting silica sand.

Limestone is made of the shells of dead ocean organisms. Their shells are made of calcite.Hope i helped1 :)
Pretty sure its paramecium (phyla - ciliophora) Their shells are the most complex and have an outer layer called a pellicle that contains defense structures called trichocysts. (just reading it from my textbook)
