Answer:
The correct answer will be Ascomycetes or sac fungi.
Step-by-step explanation:
Ascomycetes or sac fungi is a group of fungi which produce haploid spores in elongated sac like structures called asci.
Sac fungi are hetertrophic which means they can have three different methods of obtaining food. They can be saprophytes (decomposers) or parasitic (pathogens) or mutualistic. Decomposer fungi species of ascomycetes Rhizopus grows on dead or decaying organisms and take nutrition from them.
Thus, Ascomycetes is the correct answer.
