Pakati pezvakasiyana-siyana zvezvinomera uye zvipenyu zviri panyika yedu, nzvimbo inokosha inogarwa nayo mushroom, kune marudzi anenge zviuru zana, uye anokura chaizvoizvo kwose kwose. Zvichida, hapana nzvimbo yakadaro paNyika apo howa haungawani mamiriro ekukura kwavo. Howa hunokura mumasango nemuminda, mumapindu nemumafuro, mumakomo nemugwenga, muvhu nemvura.
Munhu akatanga kufarira howa kubva kare-kare. Howa hwakakamurwa kuva hunodyiwa, hunogona kudyiwa uye husingadyike (toadstools), hune chepfu. Kune kunyange sainzi yehowa - mycology - asi kunyangwe iye akatadza kupindura mubvunzo kwenguva yakareba: ndeipi nzvimbo iyo howa inogara muhurongwa hwepasi? Uye chete pakupera kwezana ramakore rechi 18 kuve kwavo kwemiti yespore kwakagadziriswa. Asi howa hunomera zvechokwadi here? Zvechokwadi, kusiyana nemiti, ivo havana chlorophyll, havakwanisi kutora carbon dioxide kubva mumhepo vari voga, uye saka vanodya pane zvakagadzirirwa-zvakagadzirwa zvinhu. Mukuwedzera, kuumbwa kwesero tishu yefungi dzakawanda kunosanganisira chitin, iyo inovaswededza pedyo nemhuka.
Nyanzvi dzezvinhu zvipenyu dzakawanda dzemazuva ano dzinosiyanisa howa semarudzi akasiyana-siyana aripo pamwe chete nezvinomera nemhuka. Howa dzakakosha zvikuru muzvisikwa uye nokuda kwebasa rehupfumi hwevanhu.
Howa zhinji dzehat (kune marudzi angangosvika mazana maviri) dzinodyiwa uye chikafu chevanhu. Howa hwave huchidyiwa kweinenge nhoroondo yose yevanhu. Maererano nemakemikari avo uye mapuroteni, howa dziri pedyo nenyama pane kudyara zvigadzirwa. Uye maererano nehuwandu uye kuumbwa kwemakhahydrates nemaminerari, ivo vachiri pedyo nemiriwo nemichero.
Kukosha kwekudya kwehowa kunotaridzirwa nekuvapo kwezvakasiyana-siyana organic compounds uye mineral salt mavari. Howa dzakapfuma mune akasiyana enzymes anokurudzira kuparara kwemafuta uye fiber. Ichi chimiro chinoratidza howa sechinhu chinodiwa uye chinobatsira chekuwedzera chigadzirwa mukudya kwezuva nezuva. Zvirimo zveshuga dzakasiyana muhowa zvinowedzera kukosha kwavo kwekudya uye zvinopa kunakidza kunotapira kuravira. Howa dzinewo mafuta anokosha, digestibility yavo inenge yakaenzana nemafuta emhuka. Mafuta anokosha anopa howa kumwe kunhuhwirira, uye resin inovapa hunhu ductility (mukaka, mamwe russula). Howa zvakare akapfuma mune zvakakosha trace elements.
Howa hutsva hunogona kuchengetwa kwemaawa mashomanana chete, saka kuitira kukohwa kweramangwana ivo vakaomeswa, vakaiswa munyu, vakabikwa, vakaiswa mumagaba.
