Symbiosis is a broad term that describes any relationship between two different species that live in close proximity. There are three main types of symbiosis:

* Mutualism: Both species benefit from the relationship.

* Commensalism: One species benefits, while the other is neither harmed nor helped.

* Parasitism: One species benefits at the expense of the other.

So, while mutualism, commensalism, and parasitism are specific types of symbiosis, the term symbiosis itself encompasses all three.
