Biotic factors for coral reefs

Biotic interactions govern the structure and function of coral reef ecosystems. As environmental conditions change, reef-associated fish populations can persist by tracking their preferred niche or adapting to new conditions.

Coral reefs-Location Coral reefs are generally found in clear, tropical oceans. Coral reefs form in waters from the surface to about 45 metres deep because they need sunlight to survive. The three types of reefs include fringing reefs, barrier reefs, and atolls. Fringing reefs occur along shorelines of continents and islands and are commonly found in Hawaii and the Caribbean. Barrier reefs are found farther offshore than fringing reefs, occurring most often in the Indo-Pacific and Caribbean. Atolls are a series of low coral islands surrounding a central lagoon, frequently found in the Indo-Pacific.

The reef covers an area over , square kilometers and includes a wide range of ocean depth, and it contains such biodiversity as to make it one of the most complex ecosystems on Earth. Much like any other ecosystem on Earth, the Great Barrier Reef relies on biotic and abiotic components to keep it functional and stable. Coral is the basis for the diverse animal and plant life in the Great Barrier Reef. Coral consists of polyps, which are very small creatures that reproduce to form colonies. These colonies of coral make up the reefs in this ecosystem. Polyps live inside shells comprised mostly of calcium carbonate, which is what most people identify as coral, as these shells are what remain behind after the polyps have died and form the structure of the reefs. Coral takes the form of antler, plate, fan or brain shapes, and groups of coral form a forest-like appearance. These biotic components of the Great Barrier Reef create a habitat for other living things. Animals such as sea turtles, crabs, sea urchins and fish act as consumers in the Great Barrier Reef ecosystem. Primary consumers in this ecosystem include zooplankton and herbivorous fish, while other fish that eat coral polyps or barnacles that eat plankton make up a group of secondary consumers. Large reef fish, sharks, eels and barracudas make up the tertiary consumers at the top of the food chain. Marine mammals such as dolphins and seals, as well as sea birds, also act as tertiary consumers.

Abiotic factors There are multiple abiotic factors that affect coral reefs figure Comparative Law. Medical Microbiology and Virology.

Fishermen are not the only ones using nets! Worm snails create a net out of mucus that can be up to several meters long. It uses the sticky net to trap plankton. It can haul in the net and then feast! Check out our blog to find out more. Corals have certain environmental conditions that they need in order to survive. These factors limit where corals can live.

Learn the risks our world's coral reefs are facing and what they mean for our future and the future of the ocean. Coral reefs are important ocean habitats and offer a compelling case of the risks of climate change. And complex compounds found in coral reefs hold promises in modern medicine. These are what we call ecosystem services that would be very difficult and expensive to replace. Can you think of any other invertebrate that people would come from afar just to see? This means the organisms cooperate with each other. The algae, called zooxanthellae, live inside the corals, which provide a tough outer shell made from calcium carbonate.
