What else can I help you with?
What do many organisms take from seawater to make bones or shells?
They take magnesium.
What uses the carbon to build their skeletons and shells?
Life on Earth is carbon based, so all animals with skeletons and shells use carbon. A more 'common' element used in skeletons and shells is calcium.
Which rock could be formed either by deposition of animal shells and skeletons or by precipitation from evaporating seawater?
Limestone is a rock that can be formed through the accumulation of animal shells and skeletons, called biogenic limestone, or through the precipitation of calcium carbonate from evaporating seawater, known as chemical limestone.
What will decrease the amount of carbon dioxide in the air?
Growing plants Chemical geological processes (happening in the Oceans). Organisms that make calcite shells (that then become buried by geological processes).
How did carbon in the atmosphere get into the shells of mussels?
Mussels absorb carbon into their shells from the ocean water. The carbon is in the form of calcium carbonate, which mussels extract from the water to build their shells. When carbon dioxide in the atmosphere dissolves in the ocean, it forms carbonic acid, which can break down to release carbonate ions that mussels use to create their shells.
How are sea shells a part of the carbon cycle?
Sea shells are composed of calcium carbonate (CaCO3) as the main constituent hence on decay and decomposition the add the Carbon back to ecosystem but when taken as food or source of calcium their carbon contnats enter in food chain.
Marine organisms such as coral and shellfish have carbon in their bodies in what forms?
Marine organisms such as coral and shellfish have carbon in their bodies in the form of calcium carbonate, which makes up their shells and skeletons. Additionally, they also contain carbon in organic molecules such as proteins, lipids, and carbohydrates that are essential for their growth and metabolism. The carbon in these organisms ultimately comes from carbon dioxide in the surrounding seawater, which they assimilate through processes like photosynthesis and feeding.
What is extracted by from water molluscs to build shells?
Molluscs extract calcium carbonate from seawater to build their shells. They secrete this mineral to form the hard outer layer that protects their soft bodies.
Where do the carbons go after you burn them for energy?
Carbon from burning fuels is released as carbon dioxide. The carbon dioxides is either absorbed in seawater and converted to sea shells or plankton, or absorbed by plants and convrted to sugars. Plant matter (both in the ocean and on land is eaten to become animal flesh or is used for energy and reconverted to carbon dioxide. Some plant matter (trees) is used as renewable fuels and converted to carbon dioxide. The carbon taken out of the system for the longest time becomes limestone or fossil fuels.
Is snails growing shells a chemical changes?
chemical change
What does most of the carbon in fossil fuels exist of?
carbon is an element, so "carbon" can't exist of anything. But the carbon found in fossil fuels are mostly from shells and dead animals or plants, after being exposed to imense heat and presure by stacking layers of sediment, plants and shells
What is a sedimentary rock that is composed of the mineral calcite which comes from evaporated seawater and animal shells?
Limestone is a sedimentary rock composed primarily of calcite that forms from the accumulation of marine organisms like shells in shallow seas and through the precipitation of calcium carbonate from evaporated seawater. It is commonly used in construction and as a raw material for making cement.
