What Is The Relationship Between Coral And Algae?

The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return the algae produce oxygen and help the coral to remove wastes.

What is the primary relationship between coral and algae quizlet?

Zooxanthellae and coral have a mutualistic symbiotic relationship. Coral obtains oxygen and organic products from the algae that live within them. These algae also help the coral remove waste. The zooxanthellae obtains needed carbon dioxide and needed nutrients from the coral.

Why is algae important to coral?

Algae is not only important to coral reefs as a primary producer in the food chain many fish depend on it as well. Many fish feed on the algae which helps the reef when there is an overproduction of algae. … If there is not enough algae the coral will die because it will not be able to acquire food and oxygen.

What is algae for coral?

Most corals contain algae called zooxanthellae (pronounced zo-UH-zan-thuh-lay) which are plant-like organisms. Residing within the coral’s tissues the microscopic algae are well protected and make use of the coral’s metabolic waste products for photosynthesis the process by which plants make their own food.

What is the relationship interaction between corals and unicellular algae called?

ABSTRACT. The symbiotic association between the invertebrate phylum Cnidaria (Coelenterate) and the unicellular dinoflagellate algae called zooxanthellae is very common. The most well-known relationship is between zooxanthellae and hermatypic or reef-forming corals.

Why is the relationship between algae and coral called a mutualism quizlet?

The corals and algae have a mutualistic relationship. The coral provides the algae with a protected environment and compounds they need for photosynthesis. In return the algae produce oxygen and help the coral to remove wastes.

What organism does coral have a symbiotic relationship with?

The relationship between coral and zooxanthellae (algae) is one of the most important mutualistic relationships within the coral reef ecosystem. Zooxanthellae are microscopic photosynthetic algae that reside inside the coral. The hard coral provides protection as well as compounds needed for photosynthesis to occur.

How does coral get energy from algae?

Corals get their food from algae living in their tissues or by capturing and digesting prey. … The algae live within the coral polyps using sunlight to make sugar for energy. This energy is transferred to the polyp providing much needed nourishment.

What is the relationship between coral and zooxanthellae quizlet?

Zooxanthellae are producers that make their own food and therefore they carry out photosynthesis The zooxanthellae gives the coral its color and oxygen. They help the coral reef form their exoskeleton. The relationship between the zooxanthellae and polyps are symbiosis or Mutualism.

What effect Microplastics have on the symbiotic relationship between the corals and algae?

Together with the photo-physiological stress response observed and previously published literature these findings support the hypothesis that microplastics disrupt host-symbiont signalling and that corals respond to this interference by increasing signalling and chemical support to the symbiotic zooxanthellae algae.

What makes up a coral reef?

A coral reef is made of thin layers of calcium carbonate

Coral polyps form a living mat over a calcium carbonate skeleton. … These colonies consist of millions of polyps that grow on top of the limestone remains of former colonies eventually forming massive reefs.

What is the interconnection of algae?

The algae use photosynthesis to produce nutrients many of which they pass to the corals’ cells. … Symbiosis also helps build reefs — corals that host algae can deposit calcium carbonate the hard skeleton that forms the reefs up to 10 times faster than non-symbiotic corals.

Is algae a green?

The land plants or embryophytes are thought to have emerged from the charophytes. Therefore cladistically embryophytes belong to green algae as well.
Green algae
Stigeoclonium a chlorophyte green alga genus
Scientific classification
(unranked): Archaeplastida
Kingdom: Plantae

What is the symbiotic relationship between coral reefs and fish?

Another important mutualistic relationship is the one between coral and herbivorous fish. Coral provides shelter and food to herbivorous fish in return for protection from natural enemies such as seaweeds.

What are some Commensalism relationships in the coral reef?

The most classic example of commensalism on reefs is the remora. Commonly called “suckerfish” or “sharksuckers” these fish (of the family Echeneidae) attach themselves to the skin of larger marine animals like sharks and manta rays via a specialized organ on what we might consider their back.

What is the symbiotic relationship between corals and sponges?

Sponges and Anemones

Sponges are longtime inhabitants of coral reefs. Using the coral skeleton as a place to anchor these sessile or stationary organisms provide shelter for fish shrimp crabs and other small animals. In both cases the symbiosis is commensal.

What is mutualism relationship?

Mutualism is a type of symbiotic relationship where all species involved benefit from their interactions.

Why do corals need a mutualistic relationship with other species quizlet?

Important mutualistic symbiotic relationship. Corals get up to 90% of their nutrients from zooxanthellae and the zooxanthellae gets protection and chemicals that they need for photosynthesis from the coral polyp. Tiny unicellular algae that live within coral polyps’ tissues. They give coral their color.

Which statement best describes the relationship between coral and zooxanthellae?

Which of the following terms best describes the relationship between zooxanthellae and corals? Explanation: (C) Most reef-building corals have a mutually beneficial symbiotic relationship with the microscopic unicellular algae called zooxanthellae.

What is the relationship between spider crabs and algae?

The spider crab and the algae have a symbiotic relationship. Spider crabs live in shallow areas of the ocean floor and greenish-brown algae lives on the crabs’ backs. The algae helps the crabs blend in with their environment and makes it unnoticeable to predators.

What happens when algae leaves coral?

Coral bleaching happens when corals lose their vibrant colors and turn white. … As the algae leaves the coral fades until it looks like it’s been bleached. If the temperature stays high the coral won’t let the algae back and the coral will die.

How does algae photosynthesis cause coral bleaching?

Coral bleaching occurs when corals are stressed by a change in environmental conditions. They react by expelling the symbiotic algae that live in their tissues and then turn completely white. The symbiotic algae called zooxanthellae are photosynthetic and provide their host coral with food in return for protection.

Is coral a reef?

A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. … They are most commonly found at shallow depths in tropical waters but deep water and cold water coral reefs exist on smaller scales in other areas.

In what ways are corals other organisms and coral reefs important to the ecosystem and to us?

Coral reefs protect coastlines from storms and erosion provide jobs for local communities and offer opportunities for recreation. They are also are a source of food and new medicines. Over half a billion people depend on reefs for food income and protection.

What is the relationship between the zooxanthellae and the hard coral?

The symbiosis between corals and zooxanthellae is supposed to be mutualistic meaning that they both receive positive benefits from their partnership. Zooxanthellae are provided with a safe place to live within the coral tissue and they also get to use the coral’s waste products as nutrients to power photosynthesis.

Why do corals become bleached quizlet?

The main cause of coral bleaching is heat stress resulting from high sea temperatures. Temperature increases of only one degree celsius for only four weeks can trigger bleaching events. If this temperatures persist longer periods (eight weeks or more) corals begin to die.

What is the relationship between the dolphin and the School of Trevallies?

Echolocation is so precise that a dolphin can determine the size direction and distance of a school of prey fish and even sizes of individual fish in the school. To feed dolphins use a fast surprise attack and unlike the hunting packs of trevallies dolphins can successfully hunt alone.

How microplastics affect corals?

When these tiny particles reach coral reefs they harm corals by constantly rubbing on them through the action of waves and currents. Corals may also ingest microplastics and get a false sense of “fullness ” which results in the coral not feeding on nutritious food.
