Sometimes, completely different species or organisms forge close or interdependent relationships, to the advantage of at least one of the parties involved. This interaction is called a symbiotic relationship.<\/p>\n\n\n\n

<\/div>\n\n\n\n

It\u2019s not easy to come up with a narrow definition of symbiosis. In fact, symbiotic relationships can be divided into several groups:<\/p>\n\n\n\n

<\/div>\n\n\n\n

Symbiosis<\/h2>\n\n\n\n

All organisms or species involved in the relationship not only benefit from it, but it\u2019s also essential or indispensable for their survival.<\/strong><\/p>\n\n\n\n

\n\n\n\n

Mutualism<\/h2>\n\n\n\n

All parties involved in the relationship benefit from it, as it improves their biological fitness<\/a>, but it\u2019s not strictly necessary for their survival.<\/p>\n\n\n\n

\n\n\n\n

Commensalism<\/h2>\n\n\n\n

Only one party involved in the relationship benefits from it, without harming the other one.<\/p>\n\n\n\n

\n\n\n\n

Parasitism<\/h2>\n\n\n\n

When a species or organism (parasite or host) benefits from the relationship at the expense of the other party (host), usually harming them.<\/p>\n\n\n\n
