Sand dollars are living organisms, similar to starfish or sea urchins. When you see them on the beach, you mostly see what is left of them after they die and decay, their calcium carbonate shell.
Sand is usually made of small particles of rock which were never alive or part of a living thing, although it is also possible to make sand out of sea shells, which are part of a living thing although they are not actually alive. Shells are a secretion of living things. No, sand was and never will be a living thing in my opinion. Maybe in evolution it was, but science is or equals observation. Since it has not been observed, it is not science. That is why evolution is still a theory.
Abiotic factors of a desert include soil, sand, gravel, rocks, water, light and air.
glass is nonliving. The non-living factors that are part of the ocean ecosystem include water, the substrate (rock or sand), and the minerals and gases dissolved in the water.
Abiotic.
No, glass is not biotic. Biotic refers to living organisms, while glass is a non-living material typically made from silica, sand, and other minerals.
No. A sand dollar is another living thing that is not plankton.
Sand dollar is not a flower. Sand dollar is a flat living marine creature. They are closely related to star fishes.
sand
It is an abiotic factor because sand is non-living and an abiotic factor is an non-living thing in an ecosystem.
the non-living things in a desert is sand and big rocks!
Sand dollar is not a limestone. It is a living thing found in the sea. They are a kind of sea urchins which are round and flat. The flat portion is its bone which is called the test.
Sand is a non-living (abiotic) material found in deserts.

Living things grow and need things to live. For example a person needs sleep, food and water in order to live. Sand doesn't grow and it doesn't need anything to live so, it is considered non-living.
Yes sand dollars are a kind of sea urchins that are flattened and can burrow itself.
Every thought that comes in our mind when we are left alone in the desert, and we dont have anything that we need is non living thing after sand.
Soil, sand, gravel, rocks, water and light are non-living factors found in a desert.
