Explanation / Answer

1. Fungi oftem associate themselves with the roots of other plants. As the fungi have long mycelium, it increases the surface area of the roots, causing increased water and nutrient absorption. This is absent in this case.

2. Fungi in the soil can break down complex detritus and increase the availability of simpler nutrients in the soil, which is also absent in this case.
