Lichens are a symbiotic relationship between what three types of organisms?

Question

A). Animal and Protist and Plant

B). Plant and Animal and Fungi

C). Archaea and Fungi and Bacteria

D). Fungi and Plant and Fungi

E). Fungi and Fungi and Protist

Answer 1

None of these! Lichens are a symbiosis between a fungus and either an alga or a cyanobacterium. Those are fungus, plant, and bacterium respectively, though I suppose cyanos might be designated archaea.

You might want to probe speciation on lichens: the symbiosis is not obligatory for all possible partnerings, though that's usually where they are found, so to speak.

And if you think that losing independence is a bad thing, consider that the majority (though not the totality) of plant species preferentially adopt fungal partners (mycorrhizae).
