A species that is involved in a facultative mutualism with another: can utilize different resources outside of the mutualism.
Explanation:
- Mutualism is a type of ecological relationship in which two organisms are related to each other in such a way that both of them could benefit from the relationship.
- A type of mutualism in which the two organism cannot depend on any other resource outside their mutualistic relationship is called obligate mutualism.
