are seashells made from calcium
The ornate shells of marine organisms like mollusks are remarkable on any number of levels, not least in the intricate coloration they often exhibit. Calcium Carbonate. The chemical compound calcium carbonate is composed of calcium, carbon and oxygen. A simplified equation for its formation would be the addition of calcium, oxygen and carbon dioxide to form CaCO3, the chemical formula for calcium carbonate. A major source of the compound is marine organisms such as coral, shellfish and mollusks, which use it to construct their shells, or skeleton-like casing. The colour that a sea shell has is not just to make the shell look pretty. It often acts as a camouflage, hiding these small animals from the predators that hunt them. That’s not all! The different shell colouring and patterns is even a means by which different species communicate with each other. Some shell fish can even change their colour to hide on the seabed when predators are near. The colour in a seashell acts as a camouflage to hide its animal from predators. Pollution and sea shells Today due to increased carbon dioxide pollution, the seas are absorbing the excess carbon dioxide. These calcium-carbonate structures also are remarkable for the transformation they can undergo under the right conditions, metamorphosing into one of the world’s most arresting and ornate rock types. Calcium Citrate is used in tofu, I believe. I do know that dolomite is a very hard to assimilate calcium, not like citrate, which is the easiest. I don't know about limestone or sea shells. Dolomite has the proper ratio calcium to magnesium (which should always be 50% of the amount of calcium. Sea shells were even used as tools and weapons. Shells of giant clams have even been used as bowls for eating food. If ground into small pieces, shells can be mixed with soil to increase calcium content in the soil and raise the pH of the soil. Generally speaking, regardless of the calcium source it tastes the same. The acid in the lime juice is used up to dissolve the calcium so it is not tart like regular lime juice. Try it. No, that's not true. Calcium citrate is a salt, and this tastes both lemony and salty. Make your own calcium supplements at home from eggshells and lime juice. Calcium Citrate (w'pedia) is one of the best types of dietary calcium. Stephanie Simpson demonstrates how to make it. Seashells contain calcium carbonate. The calcium carbonate reacts with the acid in the vinegar and causes carbon dioxide bubbles to form. Even though the acid in vinegar is weak it can, over a period of time, dissolve shells.
