Symbiosis in nature refers to a close and long-term biological interaction between two different species. This relationship can be beneficial, harmful, or neutral for one or both species involved. The organisms involved in symbiosis may rely on each other for survival, protection, or access to resources. Examples of symbiotic relationships include mutualism (both species benefit), commensalism (one species benefits while the other is unaffected), and parasitism (one species benefits at the expense of the other).
