Commensalism is a long-term biological interaction in which members of one species gain benefits while those of the other species neither benefit nor are harmed. [1] This is in contrast with mutualism , in which both organisms benefit from each other; amensalism , where one is harmed while the other is unaffected; and parasitism , where one is ...
Planktivorous fish (8, some damselfishes and triggerfishes) transfer energy from zooplankton up to reef predators like jacks (9), [101] which provide top-down control of reefs [102] and are important targets for shoreline recreational fisherfolk. [103] Grazers (10, chubs) help keep coral reefs from being overgrown by macroalgae. [104]
Commensalism is an interaction in which one species benefits and the other species is unaffected. Epiphytes (plants growing on other plants, usually trees) have a commensal relationship with their host plant because the epiphyte benefits in some way ( e.g. , by escaping competition with terrestrial plants or by gaining greater access to ...
Coral reefs are home to a variety of dinoflagellate symbiont, [10] these symbionts give coral its bright coloring and are vital for the survival of the reef. The symbionts provide the coral with food in exchange for protection. If the waters warm or become too acidic, the symbionts are expelled, the coral bleaches and if conditions persist the ...
Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef. These reefs are composed of large coral colonies of a variety of species living together. The corals form multiple symbiotic relationships with the organisms around them. [7]
Coral reefs form complex marine ecosystems with tremendous biodiversity. Marine ecosystems are the largest of Earth 's aquatic ecosystems and exist in waters that have a high salt content. These systems contrast with freshwater ecosystems , which have a lower salt content.
For instance, barnacles on whales is an example of an ectosymbiotic relationship where the whale provides the barnacle with a home, a ride, and access to food. The whale is not harmed, but it also does not receive any benefits so this is also an example of commensalism. An example of ectosymbiotic bacteria is cutibacterium acnes. These bacteria ...
Coral reefs are one of the most well-known marine ecosystems in the world, with the largest being the Great Barrier Reef. These reefs are composed of large coral colonies of a variety of species living together. The corals from multiple symbiotic relationships with the organisms around them. [21] Coral reefs are being heavily affected by global ...
