What else can I help you with?
Can too much carbon in seawater prevents clams snails and other and other sea animals from growing their shells?
Yes, excessive carbon dioxide in seawater can lead to ocean acidification, which negatively impacts the ability of clams, snails, and other marine animals to grow their shells. As CO2 levels rise, seawater becomes more acidic, reducing the availability of carbonate ions essential for shell formation. Consequently, these organisms may struggle to maintain their shells, leading to weaker structures and potentially affecting their survival and overall marine ecosystems.
What do many organisms take from seawater to make bones or shells?
They take magnesium.
Why is carbon dioxide important for the formation of shells?
Carbon dioxide plays a crucial role in the formation of shells through its involvement in the ocean's carbon cycle. When CO2 dissolves in seawater, it reacts with water to form carbonic acid, which subsequently dissociates into bicarbonate and carbonate ions. These carbonate ions are essential for marine organisms, such as mollusks and corals, as they use them to create calcium carbonate, the primary material for their shells and skeletons. Thus, adequate levels of CO2 are vital for the health and growth of these organisms and the ecosystems they support.
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.
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.
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.
A mineral that forms in seawater from the skeletons of sea creatures?
A mineral that forms in seawater from the skeletons of sea creatures is calcium carbonate, often found in the form of aragonite or calcite. These minerals are produced by marine organisms such as corals, mollusks, and certain plankton as they create their shells and skeletons. Upon death, these organisms contribute to sediment that eventually compacts and can form limestone or other sedimentary rocks. This process plays a critical role in the carbon cycle and the geological carbon sequestration of the oceans.
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.
