Explanation:
Organisms of same or different species interact in an ecosystem. The interaction of two organisms in an ecosystem is called SYMBIOSIS. A symbiotic relationship must include two organisms whose actions either benefits or harms one another.
In this question, Lichen is the term used for a symbiotic relationship between a fungi and an algae. It is called Symbiotic because two organisms are involved and those two organisms are Fungi and Alage. The symbiotic relationship between these two organisms is MUTUALISTIC in the sense that both organisms benefit from the relationship. The fungi absorbs water and nutrients from the soil while the algae supplies food via photosynthesis.
Hence, the answer is FALSE because LICHEN is a symbiotic relationship term that involves two organisms with ALGAE being one of those organisms.
