Ngabe izitshalo ziwathatha kuphi amandla?

Lapho sitshala izitshalo kwesinye isikhathi sizithola sisesimweni sokuthi zibuthakathaka, zingenamandla. Kepha lokhu kusho ukuthini ngempela? Lezi zidalwa ukuze zihlale ziphila zenza okuthile okungekho silwane esikwaziyo ukukwenza: shintsha ukukhanya kwelanga kube ukudla, kuphela ngamanzi nomoya; Kodwa-ke, uma zimbi, imisebenzi yazo ebalulekile yehlisa ijubane, futhi ngenxa yalokho, ukubukeka kwayo kuba lusizi.

Ukwazi ukuthi kubaluleke kangakanani ukuwanisela nokuwafaka umquba, kuyathakazelisa ukubuza lapho izitshalo zithola khona amandla. Futhi yilokho kanye esizokhuluma ngakho kule ndatshana, ukuze kuthi lapho uqeda ukuyifunda wazi kabanzi ukuthi zimangalisa kanjani izitshalo.

Amandla, igama elilodwa, kodwa yeka igama. Ngendlela efanayo abantu abangenamandla abakwazi ukwenza lutho ngayo, lapho izitshalo zishoda nazo ziyama, zibuthaka, futhi ekugcineni ziba sengozini yezinambuzane ezingaba izinambuzane kanye nama-microorganisms (amagciwane, isikhunta kanye namagciwane) adala izifo.

Kaningi asicabangi ngalokhu; Akumangalisi ukuthi izidalwa zezitshalo ziphila ngesikhathi esikwehluke kakhulu kwesethu. Empeleni, ngenkathi abantu ngomzuzu owodwa bekwazi ukuhamba isilinganiso samamitha ayi-89, i- imimosa ezwelayoIsibonelo, kuthatha imizuzu engu-8-10 ukuvula amashidi akho ahlanganisiwe.

Ngaphandle kwamandla ubungasho ukuthi ayikho impilo, yingakho sizochaza ...:

Zidla kanjani izitshalo?

Izitshalo zidinga ukondla, nsuku zonke. Kuzoba nezinyanga ezithile lapho inani lokudla okumunca izimpande zabo lizoba lincane, njengalapho amazinga okushisa ephansi kakhulu noma ephezulu kakhulu ukuthi angakhula kahle, kepha ngeke lube khona usuku lapho okuphakelayo. Isistimu yakho yezimpande izokwelula inqobo nje uma ithatha ukuthola amanzi, azothuthelwa phansi isiqu emaqabungeni.

Amaqabunga yizimboni zokudla zezitshalo. Emini, ukumunca amandla elanga nesikhutha (CO2) kusuka emoyeni abazoguqula kamuva kube ukudla ngenqubo eyaziwa njenge i-photosynthesis.

Yini imisebenzi ebalulekile yezitshalo?

Izitshalo kumele zenze uchungechunge lwemisebenzi ukuze zibe khona futhi zibe yilokhu eziyikho. Yize bekwenza buthule futhi, ngokombono wethu njengabantu, kancane, indlela yabo yokusinda iphelele. Ubufakazi balokhu ukuthi i-Plant Kingdom yaqala ukuvela kwayo eminyakeni engaphezu kwezigidi eziyi-1500 edlule, ngesimo se-algae; nezitshalo zokuqala 'zesimanje,' ukuzivocavoca, cishe eminyakeni eyizigidi ezingama-325 edlule. I- angiosperms, okungukuthi, izitshalo eziqhakazayo, zisanda kwenzeka kakhulu: zavela eminyakeni eyizigidi eziyi-130 edlule.

Kuthiwani ngabantu? Yebo, ama-hominid okuqala kuphela eminyakeni eyizigidi eziyi-4 edlule; okungalingana nokucwayiza uma sikuqhathanisa nesikhathi esithathwa yizitshalo. Kepha masingaphambuki.

Ake sibheke ukuthi yimiphi imisebenzi ebalulekile ukuthi isebenza kahle kanjani:

Ukuphefumula

Yebo, yebo, izitshalo nazo ziyaphefumula, amahora angama-24 ngosuku. Eqinisweni, uma bengakwenzi, bebengeke baphile. Bakwenza ngendlela efanayo nathi: ukumunca umoya-mpilo nokuxosha isikhutha. Ngakho-ke, wonke amaseli omzimba afakwa umoya-mpilo, uwavumela ukuthi enze imisebenzi yawo. Kuyathakazelisa, akunjalo?

Ukudla

Amanzi abalulekile, kepha ngaphandle 'kokudla' abengeke aphile isikhathi eside. Izimpande - uma zinazo, njengoba kunezitshalo ezithile ezibizwa ngama-parasites ezingazivezi- ukuthi lokho ezikwenzayo kumunca izakhamzimba ukuthi bathola ezweni lapho bekhula khona.

Lapho inhlabathi impofu, lesi sitshalo, emakhulwini eminyaka nasezinkulungwaneni zeminyaka, siguquka size sithole indlela ethile esivumela ukuthi sibe khona. Lokhu yilokho esidla inyama ngokwesibonelo: behlala emazweni lapho amanzi athatha khona izakhamzimba zonke, bakha izingibe eziya ngokuthuthuka ukuze babambe izinambuzane ezincane, abazondla ngazo.

Khula ubheke elangeni

Zonke izitshalo zidinga ukukhanya ukuze zikhule; abanye bayayidinga ngqo, kanti abanye ngendlela ehlungiwe emagatsheni ezihlahla. Kepha, Wazi kanjani ukuthi kufanele ukhule nezimpande phansi? Impendulo kulesi sikhuthazo yaziwa ngokuthi i-phototropism.: okokuqala kungaba yi-phototropism enhle, futhi esimweni sezimpande ayibi.

Ukukhanya kubangela ukusabela kwe-hormonal okubangelwa i-auxin, okugxilwe esifundeni esiphambene nokuqhamuka kokukhanya lapho impendulo ye-phototropic ingeyinhle, noma ngokuphambene esifundeni lapho izehlakalo zokukhanya ziqonde ngqo lapho impendulo i-phototropic ilungile.

Siyethemba ukuthi le ndatshana ibe nentshisekelo kuwe ukwazi kabanzi ngezitshalo nomhlaba wazo. Ukubazi kungasiza, futhi okuningi, ukubanakekela kangcono 😉.
