The calcium carbonate found in limestone was originally extracted from?
The calcium carbonate found in limestone was originally extracted from the shells and skeletons of marine organisms such as corals, mollusks, and foraminifera that accumulated on the ocean floor over millions of years. These organisms extract calcium and carbonate ions from surrounding water to build their calcium carbonate structures, which eventually become part of limestone deposits through geological processes.
Is chalk is composed of calcium carbonate?
Chalk is simply another form of Calcium Carbonate(CaCO3)
What is sources of calcium and sodium in oceans?
The primary sources of calcium in oceans are from the weathering of rocks on land and underwater volcanic activity. Sodium in oceans mainly comes from the weathering of rocks on land and dissolution of minerals in oceanic crust. Both calcium and sodium are essential elements for marine organisms and play crucial roles in various biological processes.
Do clam shells have calcium?
Yes, clam shells contain calcium carbonate which is a form of calcium. Calcium is a key component of shell formation in many marine organisms, including clams.
Many ocean creatures make their shells out of calcium carbonate (CaCO3). This process is more difficult when the ocean pH is lower. Why would greenhouse gas emissions harm these creatures?
Greenhouse gas emissions increase levels of carbon dioxide in the atmosphere, which leads to ocean acidification when CO2 is absorbed by the ocean. This lowers the pH of seawater, making it harder for marine organisms like shell-forming creatures to extract the calcium carbonate they need to build their shells. This can weaken their shells and make them more vulnerable to damage and predators.
Some organisms use chemosynthesis to survive where do they get the energy for this process?
from chemicals in the ocean

What is a competition in the biome from the coastal ocean?
organisms try to use the same recourse
Some organisms in the ocean use this greenhouse gas for photosynthesis and shell?
oxygen
Would you expect to find calcium chloride in ocean water?
what do you expeat to find in calcium chloride in ocean water
Is chalk made of microplankton?
No, chalk is primarily composed of calcium carbonate, a mineral made up of the skeletal remains of plankton and other marine organisms. Microplankton are tiny organisms found in the ocean, but they are not the main component of chalk.
What are the two ways which people use ocean organisms?
We use the ocean for so many things, like swimming, fishing...
When the ocean absorbs co2 the pH of the ocean water drops What is the effect of this process?
The process of the ocean absorbing CO2 leads to ocean acidification, causing a drop in pH. This can have negative impacts on marine life, particularly organisms that rely on calcium carbonate to build their shells and skeletons. Ocean acidification can disrupt the ocean's ecosystem and biodiversity.
What is the role of calcium in living organisms?
to be cool
What impact does CO2 have on the ocean?
Carbon dioxide (CO2) has a significant impact on the ocean by causing ocean acidification. When CO2 is absorbed by the ocean, it reacts with water to form carbonic acid, which lowers the pH of the water. This can harm marine life, particularly organisms with calcium carbonate shells or skeletons, as the more acidic water makes it harder for them to build and maintain their structures. Ocean acidification can disrupt marine ecosystems and have far-reaching consequences on the health of the ocean and the organisms that depend on it.
Why are large areas of sea floor covered with thick layers of sediment containing calcium?
Large areas of sea floor are covered with thick layers of sediment containing calcium due to the accumulation of calcium carbonate shells and skeletons from marine organisms over time. This process, known as biomineralization, contributes to the formation of limestone and other calcium-rich sediments.
