Many act as decomposers, breaking down the dead bodies of plants and animals and recycling the nutrients they hold. ... The fungal decay makes these nutrients and carbon dioxide available to green plants for photosynthesis, and it completes an important cycle of raw materials in the ecosystem.
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.
- A type of mutualism, in which the participating organisms can opt for other resources outside their mutualistic relatonship i.e. they are not completely dependent on each other, is called facultative mutualism.
