Answer: D. Rhizopus

Explanation

Rhizopus is a widespread zygomycete fungus commonly known by the popular moniker black bread mold. Its fuzzy black appearance on stale food comes from the dark coloration of mature asexual sporangia. Mycologists frequently study this rapid-growing mold due to its distinct colonial morphology and spore structures. Zygomycete fungi reproduce sexually through zygospores and asexually via spores produced inside spherical sporangia. Rhizopus species secrete digestive enzymes externally and absorb organic nutrients from decaying starchy substrates. Spores of this common mold drift freely through indoor and outdoor air environments around the world.

Food preservation techniques are designed to prevent black bread mold contamination in domestic kitchen environments. Certain Rhizopus strains are utilized industrially in Asia to ferment food products like tempeh from soybeans. Mycology courses use this easily cultured fungus as a standard laboratory model organism for educational demonstrations. Pilobolus is a specialized dung-inhabiting fungus known for forcefully shooting its sporangia toward sunlight. Penicillium is a famous ascomycete mold recognized for producing the antibiotic penicillin and blue cheese flavors. Neurospora is a pink bread mold widely utilized by geneticists as a model organism for inheritance studies.
