Fungi feed through extracellular digestion and then absorption. How would the rates of decomposition of detritus be altered if fungicide (something that kills fungi) were sprayed on the forest floor?
A. Decomposition rates would be lowered
because fungi would be destroyed.
B. Decomposition rates would be higher
because bacteria would take over the role of
decomposition, and they reproduce at faster
rates than fungi.
C. Decomposition rates would be the same
because fungi don't have hyphae above
ground, so they would not be destroyed.
D. Decomposition rates would be lowered
because fungi would choose to grow in an
area without fungicide.
