Dead echinoderms are naturally recycled to make which product?

Calcium Carbonate CaCO³

Explanation:

All echinoderms possess a calcitic exoskeleton this structure is manly built of calcium carbonate which is a crucial compound for the development of different animals such as corals and other. Hence if they died after decomposing the material will slowly dissolved back into the ocean

segmentation=endoskeleton=backbone=coelom=tissues

for  example, forests have higher evapotranspiration than other ecosystems,  such  as grasslands, because of their deeper roots and greater leaf area. thus forests have a net moistening effect on the atmosphere and become a moisture source for downwind ecosystems.
