How do you know that coral are under stress in their habitats?

You would know if coral is under physical stress if it is bleached. Coral bleaching occurs when the coral polyps (the miniscule animals that coral is made of) expel their algal cells, and the coral looks white. If the coral stays bleached for too long, then it can die.


Which of these is the underwater buildup of limestone skeletons from certain small animals?

The correct term is "coral reef." Coral reefs are formed by the accumulation of calcium carbonate skeletons secreted by coral polyps over time.


Why don't sharks swim into coral reef areas?

Sharks are cautious animals and generally avoid areas with a lot of obstacles like coral reefs that could potentially injure them. They prefer open waters where they can move freely and have access to their prey. Additionally, the structures of coral reefs are not ideal for their hunting strategies.


Research how coral reefs are formed. What types of animals live there What important roles do cnidarians play in coral reefs How do the tiny animals get their food How do algae help the corals?

Coral reefs are formed in shallow, warm, and clear bodies of water, such as oceans and seas, where the ocean temperatures are consistently between 64 and 82 degrees Fahrenheit. The reefs are formed by tiny creatures known as cnidarians, or “stinging cells”. These organisms are filled with stinging cells that they use to capture prey. Coral reefs are home to a variety of animals including fish, mollusks, crustaceans, and sea turtles. These animals take shelter in the coral and feed on the nutrients available in the reef. Cnidarians play an important role in coral reefs as they provide food for the other animals. They also help keep the coral clean by consuming the dead material in the reef. Cnidarians get their food by catching tiny crustaceans and other small organisms, as well as by consuming the microscopic plankton that is present in the reef. Algae also help the corals by providing them with essential nutrients, such as nitrogen and phosphorus, which are necessary for the growth of the coral. Algae also provide oxygen, which helps keep the coral healthy. Additionally, algae help to keep the reef environment stable by absorbing excess carbon dioxide and nutrients that can be harmful to the coral.


Is coral a living thing?

Coral reefs have a non-living component, in the form of a calcium carbonate skeleton, and a living component in the form of small animals called polyps, who secreted the skeleton. However, if the polyps die, you still have coral left over, so coral can be either living or dead.

Do coral reefs have bones?

Yes. Coral is both the living and skeletal remains of Marine organisms. These in effect are the bones of the animals.

Which rock was formed from skeleton and shells of sea animals and plants?

Limestone is a rock that is formed from the skeletal remains of sea animals and plants. It is primarily composed of calcium carbonate, which is derived from the shells and skeletons of marine organisms such as coral, mollusks, and foraminifera. Over time, these remains accumulate and become compacted and cemented to form limestone rock.


Is dead coral a rock or a mineral?

Dead coral is a rock because it is composed of the skeletal remains of marine organisms called coral polyps that have hardened over time. It is made up of the mineral calcite, which is a crystalline form of calcium carbonate.


What type of sedimentary rock forms from carbonate minerals precipitating from freshwater springs?

What is an island formed by the remains of sea animals?

An island formed by the remains of sea animals is known as an atoll. Atolls are composed of coral reefs surrounding a lagoon, often formed on top of submerged volcanic islands. The coral reefs are built up over thousands of years by the accumulation of calcium carbonate skeletons from coral polyps.


Where did you probably find a deposit of limestone what type of setting did it form in?

Limestone is formed on the floor of ancient seas from the skeletal remains of marine organisms such as coral, forams and molluscs, etc.

Does sand form when ocean animals crush rocks and push the remains to the shore?

No. Sand is mostly produced by rocks being ground down in rivers. Coral sand is made from the dead bodies of coral.
