Afungus on the roots of a plant the plant absorb nutrients it needs from the soil, while the fungus gets what it needs from the plant. what type of symbiotic relationship is this?
a. mutualism
b. commensalism
c. parasitism
d. competition

The answer is a. Mutualism.

Mutualism is a relationship between two different species in which both species have benefits. A mutualistic relationship between fungi and plants is known as mycorrhiza. In mycorrhiza, the fungi get the product of photosynthesis in plants, and plants absorb nutrients (phosphorus and nitrogen) through fungi.

Commensalism is a relationship between two species in which only one of them has benefit, and the other one is not affected. Parasitism is a relationship between two species in which only one of them has benefit, and the other one is harmed. Competition is a contest between two different species or between organisms inside one species.
