Question

How does symbiosis benefit the organisms that make up a lichen?
Each organism absorbs minerals produced by the other.
It reduces the effect of pollution and other toxic chemicals on both organisms.
It allows the organisms to live in environments where neither could live alone.
One organism eats the other to provide chemicals or nutrients missing from its environment.

Answer 1

Answer:

Each organism absorbs minerals produced by the other

Explanation:

Lichen is a symbiotic association between fungi and alga. The fungus is able to absorb essential mineral ions like calcium, phosphate and potassium better than the alga thus benefiting the alga. The fungus in return gets organic materials from the alga. The alga provides organic nutrients for the lichen through photosynthesis and the lichen provides protection from drying out because the alga lives within the fungus's cell wall.
