What is the material that hermatypic corals secrete to form their hard cup-like exskeleton?
Calcium carbonate
How does algae benefit the corals?
Many corals, specifically hermatypic corals, contain symbiotic algae that provide the coral with sugar from photosynthesis. Algae also feed zooplankton, which corals feed on. Basically, algae provide corals with food, indirectly.
What does hermatypic coral eat?
Hermatypic corals are those corals that secrete a calcium carbonate skeleton and contribute to the building of reefs. The tissues of these corals contain a symbiotic alga called zooxanthellae. These algae are able to use sunlight to create their own food, and thus give some of this food to the coral. The corals themselves are able to catch and eat both phytoplankton (microscopic plant-like plankton) and zooplankton (microscopic animal plankton) with their tentacles.
What are some differences between mangroves and coral reefs?
1). is mangroves grow above water and corals don't 2). corals are very frigaile mangroves are strong
What time of year can coral reproduce?
Usually during the month of November coral spawn in the Great Barrier Reef area, during night time. About 75% of all hermatypic corals "broadcast spawn" by releasing eggs.
Difference between cnidarians and corals?
There is none. Corals are cnidarians.
What types of coral are there?
(In the world) There are over 500,000 species in the 600,000 square miles of coral reefs. Millions of species of fish, eels, sponges, grasses, algae, mollusks, crabs, worms, and other marine animals use reefs as homes or as nurseries for their young. Tons of coral make up the coral reefs. After the coral dies, it leaves its skeletons, made of calcium carbonate, behind. There are three different kinds of reefs: fringing reefs, barrier reefs, and atolls. The reefs that are near shore and are separated from land by low water are called fringing reefs. Reefs that are at least 10 kilometers away from land are called barrier reefs. A circular coral island that is far away from land is called an atoll. Atolls form when coral develops on a volcanic island that has sunk below the water. For any of these reefs to form takes hundreds of years. It may take up to 100 years for an inch of coral reef to grow. hope this has helped you.
What is the main difference Between hard and soft corals?
The difference is in the name; soft corals are soft have body ; with no bony or hard Parts
What is a colourful predator that darts between corals?
miniatus grouper
What is the difference between hard corals and soft corals?
The difference is in the name; soft corals have a soft body, with no bony or hard parts. In contrast, hard corals have a hard endoskeleton made of calcium carbonate.
Why soft corals live in deeper water than hard corals?
soft corals live deeper water than hard corals because soft corals do not create a hard outer skeleton as the hard corals do.
Do crabs live on the Ocean floor?
Absolutely, there are many hundreds of different species of crabs that live on coral reefs. Many of them have close associations with the corals, such as the Acropora crabs, which live in between the branches of Acropora corals, and eat the slime that the corals produce.
