Sedimentary rock that is cemented with organic materials from once living organisms is called:

Explanation:
Bioclastic describes rocks formed from the remains of once-living organisms or cemented by materials produced by organisms. The grains come from biological debris—shells, fragments of corals, or plant material—and the rock is bound together by a biogenic influence, often with carbonate cement that originates from organisms. This is different from clastic rocks, which are simply made of fragments of preexisting rocks bound by mineral cement; siliciclastic rocks are a subset where the cement and grains are silica-rich; and organic rocks form from abundant organic matter rather than biogenic debris bound together. So the description fits bioclastic rocks.
