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.
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.
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.

Birch includes animals, plants, fungi, and microbes among critical interactions with humans: [9] plants too are incredibly important determinants: for mobile hunter-gatherers, they might dictate a seasonal move; for sedentary agriculturalists, the reliability of your crop yields means the difference between survival and extinction.
The mycobiome is relevant to human physiology as fungi may be important in maintaining microbial community structure, metabolic function, and immune-priming. [29] [30] Mutualism between humans and fungi is not yet well understood, and there is much to be learned about how fungi interact with the nonfungal constituents of the microbiome.
Fungi are renowned for their poisons to deter animals from feeding on them: even today humans die from eating poisonous fungi. A natural consequence of this is the virtual absence of obligate vertebrate fungivores, with the diprotodont family Potoridae being the major exception.
The Fungi are classified as a kingdom that is separate from plants and animals. The discipline of biology devoted to the study of fungi is known as mycology or fungal biology, which is historically regarded as a branch of botany , even though genetic studies have shown that fungi are more closely related to animals than to plants.
