Fungi, like the one that causes athlete's foot, are considered
a. photoautotrophs.
b. saprobic.
c. heterotrophs.
d. chemoautotrophs.

The correct answer is B. saprobic. The fungi that's there feeds off of your dead skin and spread and develops which in turn produces more dead skin and they feed even more and that's what saprobic means basically, an organism that feeds off of dead matter. The dead skin on top of your normal skin is what makes it saprobic.

Yes all of them are right
