Question

The scarlet cup fungus (Sarcoscypha coccinea) obtains its nutrition from decaying wood by releasing digestive enzymes into the wood and absorbing the digested products.

I. Autotroph
II. Heterotroph
III. Saprotroph
A. III only
B. II and III only
C. I and III only
D. I, II and III

Answer 1

II and III only. The fungus is a heterotroph, since it's not making it's own food, but it's also a Saprotroph (since it externally digests dead organic materials; saprotrophs are a special subset of heterotrophs).
