Question

Explain symbiotic relationship?

Answer 1

Hint: Symbiotic relationship shows the relation between different species. At least one species gets benefit from the relationship. Relationships can be positive, negative or neutral. Mutualism, commensalism and parasitism, predation, and competition are some symbiotic associations between different organisms. Symbiotic association helps in evolution.

Complete step by step answer: Symbiosis is the process showing symbiotic relationship between different organisms. These organisms are termed as symbionts. Symbionts either entirely depend on each other for survival or it can be optional when they generally live independently. Albert Bernhard Frank used the term symbiosis to show mutualistic relationships in lichens. When the organisms form a single body by physical attachment, this type of association is called conjunctive symbiosis. All other types of arrangements are disjunctive symbiosis.
Symbiosis association can be of two types: Ectosymbiosis occurs when one organism’s lives on the surface of another like head lice and Endosymbiosis in which on organism’s lives inside the tissues of another such as Symbiodinium within coral.
Mutualism is a long term relationship between individuals and different species where both the individuals are benefitted. An example of Ocellaris clownfish that dwell among the tentacles of Ritteri sea anemones shows mutualistic relationships. Many organisms show completion among them for the same resource there only one species can survive which is strong. Predation and parasitism are a type of symbiotic association in which only an individual is benefitted while others lose its efficiency.
Commensalism is the association in which one organism benefits greatly from symbiosis. In parasitism, one organism takes nutrition from and survives on it. In predation one organism and other as prey of other organisms.

Note: Symbiosis between bacteria and archaea helps in the development of eukaryotes by the process of symbiogenesis. This can be observed as different organelles have their own DNA. Mycorrhizas and Acacia ants show symbiotic relationships. About 80 percent of individuals show symbiotic relationships. Cattle egrets and cattle show commensalism. Barnacles on the body of whales are an example of parasitism.
