Suppose that, while on a forest hike, you notice a blue fungus and a pink plant growing along the hiking trail
As you continue walking, you observe that if a blue fungus and a pink plant are growing side by side, they are both much larger than if the fungus and the plant are farther apart. What can you hypothesize about the relationship between the fungus and the plant? A) The fungus and the plant have a symbiotic relationship that allows them to have more significant growth when they are near each other than when farther apart.
B) The fungus and the plant have a parasitic relationship that allows them to have more significant growth when they are near each other than when farther apart.
C) The roots of the plant are choking off nutrient flow to the fungal hyphae.
D) The plant is helping the fungus decompose leaf litter on the forest floor.
