Symbiosis Definition

Symbiosis refers to the close relationship amongst two different organisms or living things belonging to different species.

Symbiosis is a relationship that exists between two organisms. There are three types of behaviours observed in symbiotic relationships, namely:

  • Mutualism
  • Commensalism
  • Parasitism

In mutualism, both the involved organisms benefit from each other. In commensalism, only one organism benefits, while the other is neither benefited nor harmed. In parasitism, one organism is benefited while the other organism is harmed.

Understanding symbiotic relationships are important, as it helps us understand how various organisms are dependent on each other for survival.
