The definition of symbiosis was a matter of debate for 130 years. [7] In 1877, Albert Bernhard Frank used the term symbiosis to describe the mutualistic relationship in lichens . [ 8 ] [ 9 ] In 1878, the German mycologist Heinrich Anton de Bary defined it as "the living together of unlike organisms".
Ectosymbiosis is defined as a symbiotic relationship in which one organism lives on the outside surface of a different organism. [3] 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 best-studied examples of endosymbiosis are in invertebrates. These symbioses affect organisms with global impact, including Symbiodinium (corals), or Wolbachia (insects). Many insect agricultural pests and human disease vectors have intimate relationships with primary endosymbionts.
Mutualism describes the ecological interaction between two or more species where each species has a net benefit. [1] Mutualism is a common type of ecological interaction. Prominent examples are: the nutrient exchange between vascular plants and mycorrhizal fungi, the fertilization of flowering plants by pollinators,
Essay on the Theory of Symbiogenesis, [14] he wrote, "The theory of symbiogenesis is a theory of selection relying on the phenomenon of symbiosis." [ 15 ] These theories did not gain traction until more detailed electron-microscopic comparisons between cyanobacteria and chloroplasts were made, such as by Hans Ris in 1961 and 1962.
Symbiosis includes three types of interactions—mutualism, commensalism, and parasitism—of which only mutualism can sometimes qualify as cooperation. Mutualism involves a close, mutually beneficial interaction between two different biological species, whereas "cooperation" is a more general term that can involve looser interactions and can ...

Symbiosis is a close, long term relationship between organisms of different species. Symbiosis can be ectosymbiosis (one organism lives on the surface of other organism) or endosymbiosis (one organism lives inside other organism). [41] Symbiotic relationship can also exist between microorganism that live closely together in a given environment ...
