Solution: Fungi are eukaryotic heterotrophic organisms. The kingdom fungus includes black dots on stale bread, yeast (which is used to make bread and beer), white spots on mustard leaves, and mushrooms. Fungi can only multiply and flourish in moist, warm environments. Furthermore, there are approximately 2,000 different species of fungi identified.

| Mode of nutrition | They are saprophytes or a parasites | They are Decomposers, Saprophytic or parasitic, or coprophilous | They are Saprophytic | They are Decomposers, Saprophytic or parasitic |
| Mode of reproduction | Their mode of reproduction is Asexual reproduction by zoospore (motile) Aplanospore (non-motile) Sexual reproduction – zygote can be similar or dissimilar in morphology | Through asexual spores called conidia and sexual spores are known as ascospores | By vegetation reproduction through budding. Fusion of two somatic cells for the formation of basidiospores is Plasmogamy | Through asexual spores called conidia. |
