Magine that fungal hyphae were as thick as a human hair. How might this increase in thickness affect the ecological role of fungi? A. Their rates of decomposition of detritus would decrease because their ratio of surface area to volume would be decreased. B. Their rates of decomposition of detritus would increase because their ratio of surface area to volume would be increased. C. There would be no effect on the rates of decomposition of detritus. D. There would be no effect on the rates of decomposition of detritus because the fungi would still be heterotrophic.
