The major mineral present in the shell of Molluscs is________

Answer Details
The major mineral present in the shell of molluscs is Calcium. Molluscs are a group of organisms that includes snails, clams, and mussels. Their shells serve as a protective covering and are made of calcium carbonate, which is a mineral that is abundant in seawater. Calcium is essential for the formation and hardening of the shells and is continuously incorporated into the shells as the mollusc grows. This helps to maintain the strength and structural integrity of the shell and provides protection from predators, extreme temperatures, and other environmental factors.
