Figure 29.1

-After looking at Figure 29.1 above, why do you think the spike in fungal abundance ended so "abruptly"? Why didn't fungal abundance remain high?

A) The sudden increase in carbon from the plants' mass extinction was not sustained.
B) The plants recovered and outcompeted the fungi, thereby decreasing fungal numbers.
C) As the acidity of the environment increased, fungi were not able to survive.
