Algae
Yes, they do; symbiont green algae are called zoochlorellae.
No. A parasite feeds on its hos while keeping it alive, which is not the case with a shrimp eating algae.
In theory....no, the hair algae doesnt kill corals, what does kill the coral is hair algae growing profusely next to it preventing the coral extending its polyps and getting sun light. Algae can cover the 'mat' of some species of coral such as xenia and star polyps also preventing the polyps from extending and getting nutrients and sunlight. = = Another possibility is that some conditions that favor algae may not favor the life of the coral such as temperature of the wate and pH of the water.
The algae helps the coral by producing oxygen and other nutrients that are required by the coral. The coral produces carbon dioxide for the algae as well as other substances the algae requires.
Coral polyps are tiny animals that build protective calcium carbonate skeletons around themselves. Coral polyps create the basic structure of coral reefs with the help of single-celled algae.
Organisms that live together have the following types of (symbiotic) relationships:Commensal: One organism benefits while the other is unaffected. Algae grows in the fur of tree sloths. It is difficult to prove that the host is not affected...In this example, the sloth may benefit from the camouflaging color or, it may be harmed by the extra weight that it has to carry around.Parasitic: Host suffers to support the parasite. There are few examples of plants that are parasitic on animals.Mutualistic: Both organisms benefit from the relationship. Algae lives in the tissue of coral polyps. The coral benefits from the food that the algae produce and the algae has a well-protected home.
Malaria is caused by protozoa. This parasite has probably evolved from algae. This parasite have plasmid body, present in them, which is there in plant kingdom only.
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.
It's a mutualistic symbiosis, and occours in corals, jellyfishes and other polyps.* The symbionts, called zoochlorellae if they are green algae or zooxanthellae if they are protozoans, with photosynthesis produce: # Sugars, wich can feed the host up to 90% of its energy request. # Oxygen. * The cnidarian (coral, jellyfish or hydropolyp) gives to zoochlorellae (or to zooxanthellae) his products of waste: # CO2 (which decreasing helps hermatypic corals forming their skeletons) # Minerals. # Nitrogen. In order to perform photosynthesis, zoochlorellae and zooxanthellae need light, so they can stay only in shallow waters.
No; although clams filtrate water, they are not able to crawl on surfaces eating algae like snails do.
They are polyps in children
