  • Define symbiosis, including the characteristics of mutualism, parasitism, and commensalism.<\/strong><\/li>\n
  • Provide examples of organisms in mutualistic, parasitic, and commensalistic relationships.<\/strong><\/li>\n
  • Describe different forms of endosymbiosis including how organisms are impacted.<\/strong><\/li>\n<\/ul> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

    The next section introduces symbiosis, a close association between organisms of different species.\u00a0 These close relationships can have impacts that are positive, negative, and even neutral.<\/h5> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

    We use the word “symbiosis” in everyday language to mean getting along together, like having a symbiotic relationship with a roommate.\u00a0 In biology, symbiosis means living closely together, sometimes for long periods of time, and the outcome is not necessarily beneficial for all participants.<\/h5> <\/div>\n<\/div>\n <\/div>\n <\/div>\n <\/div>\n

    \n Mutualism <\/h3>\n
    \n Both species in the interaction benefit. Lichens are typically an example of mutualism: the algae or cyanobacteria have a place to live and the fungus receives nutrients. <\/div>\n \n <\/div>\n \n <\/div>\n <\/div>\n

    \n Parasitism <\/h3>\n
    \n One species benefits, the other is harmed but typically not killed. Lice get a blood meal and it typically does not kill the host. <\/div>\n \n <\/div>\n \n <\/div>\n <\/div>\n

    \n Commensalism <\/h3>\n
    \n One species benefits, the other does not appear to be impacted. Moss growing on tree limbs get access to sunlight, but the trees can grow and reproduce as well without them. <\/div>\n \n <\/div>\n \n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n <\/div>\n
