The researchers then wanted to know if plant biodiversity and productivity would increase in a natural system as a result of increasing AMF diversity beyond just four species. Consider Figure 31.6 below (Figure 2 from van der Heijden et al. 1998):

Figure 31.6
-If the number of mycorrhizal fungal species increases to 20,the amount of P in the soil will likely decline to zero (Figure 31.6).True or false?

Quizplus · Accepted Answer

The presence of mycorrhizal fungi generally enhances phosphorus uptake by plants, but it does not cause the phosphorus levels in the soil to decline to zero.
