Mushrooms, moulds and yeast do not make their own food — they absorb it, breaking down dead leaves and logs and returning minerals to the soil.
What is Kingdom Fungi?
- Fungi are mostly multicellular eukaryotes with cell walls of chitin (yeast is an exception — unicellular, but has a chitin wall).
- They do not make their own food; they absorb nutrients from dead or decaying matter through fine filaments that form a network called mycelium .
- Most are saprophytes and decomposers ; some are symbiotic and some parasitic. They reproduce by spores — e.g. mushrooms, Aspergillus , Penicillium (used for enzymes and antibiotics).

Mushroom cultivation is a promising livelihood — easy and accessible, needing little space, low investment and a fast life cycle (30–45 days).
