Rhizopus and Spirogyra are both types of fungi and algae, respectively. Rhizopus is a genus of filamentous fungi known for its role in decomposition and as a common bread mold, characterized by its dark, fuzzy appearance.

While Rhizopus is a heterotrophic organism that feeds on organic matter, Spirogyra is autotrophic, using photosynthesis to produce its own food.
