Is Calcium fat soluble or water soluble?

Calcium is water soluble, but not fat soluble. It is the fifth most dissolved ion in seawater. On the other hand, fat is soluble into calcium in the body. The calcium will extract the fat from food in the digestive system, and they combine to form a foamy substance which is not absorbed by the body, and so the fat will be flushed out.


What is coral formed from?

The active agent in coral formation is a small animal called a polyp. The coral you see is a protective shell (like clam's shell) the polyp makes from calcium carbonate which the polyp extracts from seawater. As each tiny polyp dies its calcium carbonate shell is covered over by succeeding generations of polyps and their calcium carbonate homes.


When you mix calcium in seawater with carbon dioxide what is the new substance that formed?

What are the organisms that live in colonies of polyps and secrete an exoskeleton of calcium carbonate?

corals


How does algae benefit from living insdie coral polyps?

When a coral polyp is formed it takes in the algae and the algae carries onto photosynthesis inside the coral. The algae later helps the coral change calcium salts in seawater into a hard calcium carbonate structure that makes up a coral reef. Without the algae helping to create calcium carbonate, a coral reef wouldn't have it's nice structure.


What is the name of the creature who makes coral?

Coral reefs are formed by polyps that produce a hard shell of calcium carbonate. The polyps belong to a group of animals known as Cnidaria.


Does the skeleton of a Coral remain?

No, the skeleton of coral polyps remains after the coral organism dies. Coral colonies are made up of thousands of tiny coral polyps that secrete calcium carbonate to build a protective skeleton structure. When the polyps die, their hard skeletons remain and new polyps build on top of the old structures, creating large coral reefs over time.

What is a calcareous skeleton?

Its when a sea animal forms a skeleton from calcium carbonate (CaCO3). Calcium carbonate is dissolved in seawater, but less soluable at higher temperatures. The majority of animals with calcareous skeletons, such as corals, are found in the tropics where it takes less energy to get it out of the seawater
