calcium carbonate will be left available to the organisms that use it to
build shells.

calcium carbonate incorporates proteins or other strength -
building components, the team turned to atomic force microscopy, also known as AFM, at the Molecular Foundry, a DOE Office of Science User Facility at Lawrence Berkeley National Laboratory.

carbonate ion, needed to make aragonite and calcite, two forms of
calcium carbonate that many marine organisms use to
build their shells and skeletons.

As each individual
builds its own
calcium carbonate living chamber, its chamber is joined to adjacent ones to make a rigid solid mass, rather like a large apartment complex.
Growth is in an upward and outward direction with individuals slowly
building the walls of their living chambers higher and depositing more floor underneath them, leaving the interior of the coral a lifeless mass of
calcium carbonate.
The first step is to collect the basic
building blocks:
