Fungi have appeared, too, from time to time, in literature and art. Fungi create harm by spoiling food, destroying timber, and by causing diseases of crops, livestock, and humans. Fungi, mainly moulds like Penicillium and Aspergillus, spoil many stored foods. Fungi cause the majority of plant diseases, which in turn cause serious economic losses.
Fungi, like animals, are heterotrophs; they acquire their food by absorbing dissolved molecules, typically by secreting digestive enzymes into their environment. Fungi do not photosynthesize . Growth is their means of mobility , except for spores (a few of which are flagellated ), which may travel through the air or water.
It is probable that these earliest fungi lived in water, and had flagella. [5] However, a 2.4-billion-year-old basalt from the Palaeoproterozoic Ongeluk Formation in South Africa containing filamentous fossils in vescicles and fractures, that form mycelium-like structures may push back the origin of the Kingdom over one billion years before.

By decomposing these molecules, fungi play a critical role in the global carbon cycle. Fungi and other organisms traditionally recognized as fungi, such as oomycetes and myxomycetes (slime molds), often are economically and socially important, as some cause diseases of animals (including humans) and of plants.

Human interactions with microbes include both practical and symbolic uses of microbes, and negative interactions in the form of human, domestic animal, and crop diseases. Practical use of microbes began in ancient times with fermentation in food processing ; bread , beer and wine have been produced by yeasts from the dawn of civilisation, such ...
Animals and fungi are also more closely related to amoebas than to plants, and plants are more closely related to the SAR supergroup of protists than to animals or fungi. [citation needed] Animals and fungi are both heterotrophs, unlike plants, and while fungi are sessile like plants, there are also sessile animals.
In recent years, meat alternatives have been growing in popularity, but unlike plant-based products, which use protein such as soy or peas to mimic real meat, and products that use the ...
The names of some protists (called ambiregnal protists), because of their mixture of traits similar to both animals and plants or fungi (e.g., slime molds and flagellated algae like euglenids), have been published under either or both of the botanical and the zoological codes of nomenclature.
