On a hike through the forest, you notice a circle of "mushrooms," each with a stalk, cap, and gills on the underside of the cap. If you dig into the soil below the ring, which of the answer choices might you find?

a. low-nutrient soil

b. moist soil

c. a net of fungal mycelia

d. remnants of a decaying tree

The correct answer is a. "low-nutrient soil".

Explanation:

The circle of mushrooms, also known as the fairy ring or elf circle because of the folklore around it, is a naturally occurring formation that certain species of mushrooms tend to develop. This formation is developed when an individual fungus grows underground and sprouts mycelium in a circular shape. If you dig in the soil beneath the circle of mushroom is likely that you will find a low-nutrient soil, because this condition is what lead the individual fungus to sprouts the mycelium in a circular shape.
