Answer 2

The Function Not Performed by Mollusk Shells

Mollusk shells serve several important functions for the organisms that possess them. However, one function that mollusk shells do not perform is respiration. Unlike gills or lungs, mollusk shells do not directly facilitate the exchange of gases between the organism and its environment.

Mollusks have evolved various mechanisms for respiration, depending on their specific adaptations and habitats. Some mollusks, such as bivalves like clams and mussels, have specialized structures called gills that are responsible for extracting oxygen from water. Other mollusks, like snails and slugs, have developed a modified respiratory organ called a lung, which allows them to breathe air.

While mollusk shells provide protection, support, and a site for muscle attachment, they do not directly participate in the respiratory process. Instead, the shells primarily serve as a protective exoskeleton, shielding the soft tissues of the mollusk from predators, physical damage, and desiccation.
