A seashell may refer to the non-living covering of a living mollusc, or it can refer to the living mollusc itself. So it depends on the context; in any case, the seashell is or was part of a living thing.
The chemical composition of a seashell (mostly calcium carbonate) is not a living tissue, but it is connected to (and constructed by) living tissue, just as skin, hair, bones, and teeth are in mammals. When the mollusc dies, the seashell is dead material. But since it is not an organic compound, it is not broken down as other animal tissues are. Similarly in plants, the structures of coral reefs persist because they include minerals not usually broken down by detrivores.
The shell itself is not living, no. If the shell is inhabited then the muscle inside of it is most certainly living.
Non living hope it helps
living
The shells themselves are non-living.
Ya Fa
Seaweed is a living organism. It is a eukaryotic protista.
It can't because it is NOT a living organism.
Nonliving
Water, salt, dissolved gases, rocks, sea shells, and sometimes oil/trash.
As long as these are just shells - meaning no living animals inside them - you will be OK.
dirt, sand, rocks pretty much every things living
NOnliving, biotic is living
the earth is nonliving but has living organisms on it
nonliving
it is nonliving
