Explanation:
Organisms in an ecosystem interact with one another from time to time. The close interaction between two organisms is referred to as SYMBIOSIS. Symbiosis is of different types depending on the how it affects the involved organisms. The example in this question depicts MUTUALISM.
Mutualism is the type of symbiotic relationship between two organisms in which both organisms benefit from the relationship. This is the case of the LICHEN, which involves the Algae and Fungi. The algae benefits by making use of the water and minerals supplied by the fungi while the fungi benefits by using the food the algae produces via photosynthesis.
