Koj puas paub tias cov tsiaj uas nyob hauv lub ntiaj teb no noj tau thiab muaj zog li cas? Peb paub tias tsiaj tau txais lub zog thaum lawv noj, tab sis li cas txog, piv txwv li, algae lossis lwm yam tsiaj uas tsis muaj qhov ncauj thiab lub plab zom mov?

Nyob hauv tsab xov xwm no peb yuav pom cov ntsiab lus ntawm autotrophic thiab heterotrophic beings, the qhov txawv ntawm autotrophic thiab heterotrophic khoom noj khoom haus thiab qee qhov piv txwv kom nkag siab zoo dua. Txuas ntxiv nyeem tsab xov xwm kom paub ntau ntxiv txog cov tsiaj uas muaj nyob hauv peb lub ntiaj teb!

Definition of autotroph and heterotroph

Ua ntej piav qhia lub ntsiab lus ntawm autotroph thiab heterotroph, nws tseem ceeb heev kom paub tias carbon yog dab tsi. Carbon yog cov tshuaj lom neeg ntawm lub neej, nws muaj peev xwm txhim kho nws tus kheej hauv ntau txoj hauv kev thiab tsim kev sib raug zoo nrog ntau cov tshuaj lom neeg, ntxiv rau, nws lub teeb hnyav ua rau nws lub ntsiab zoo meej rau lub neej. Peb txhua tus yog tsim los ntawm carbon thiab, nyob rau hauv ib txoj kev los yog lwm yam, peb yuav tsum coj nws los ntawm ib puag ncig peb.

Ob lo lus autotroph thiab heterotroph muab los ntawm Greek. Lo lus "autos" txhais tau tias "los ntawm nws tus kheej," "heteros" yog "lwm yam," thiab "trophe" txhais tau tias "nourishment." Raws li qhov etymology no, peb nkag siab tias ib tug autotrophic yog tsim nws tus kheej cov zaub mov thiab ib tug heterotrophic yog xav tau lwm tus noj nws tus kheej.

Basic of autotrophic and heterotrophic food - Qhov txawv thiab xav paub

Autotrophic khoom noj

autotrophs tsim lawv tus kheej cov zaub mov los ntawm kev kho cov pa roj carbon, uas yog, autotrophs tau txais lawv cov pa carbon ncaj qha los ntawm carbon dioxide (CO2) uas tsim cov huab cua peb ua pa los yog yaj hauv dej, qhov no inorganic carbon lawv siv los tsim cov organic carbon tebchaw los tsim lawv cov hlwb. Qhov kev hloov pauv no yog ua los ntawm lub tshuab hu ua photosynthesis.

Photosynthesis yog cov txheej txheem uas cov nroj tsuag ntsuab thiab lwm yam kab mob hloov lub teeb lub zog mus rau hauv tshuaj zog. Thaum lub sij hawm photosynthesis, lub teeb lub zog yog ntes los ntawm ib tug organelle hu ua chloroplast, tam sim no nyob rau hauv lub hlwb ntawm cov kab mob no, thiab yog siv los hloov dej, carbon dioxide, thiab lwm yam minerals rau oxygen thiab lub zog-nplua nuj organic tebchaw.

Heterotrophic khoom noj

Ntawm qhov tod tes, heterotrophic beings tau txais lawv cov zaub mov los ntawm cov organic muaj nyob rau hauv lawv ib puag ncig, lawv tsis tuaj yeem hloov cov pa roj carbon inorganic rau hauv cov organic (cov protein, carbohydrates, rog …). Qhov no txhais tau hais tias noj lossis nqus cov khoom uas muaj organic carbon (txhua yam muaj sia thiab nws cov pov tseg, los ntawm cov kab mob mus rau tsiaj txhu), xws li cov nroj tsuag lossis tsiaj txhu. Tag nrho cov tsiaj thiab cov fungi yog heterotrophs

Muaj ob hom heterotrophs: photoheterotroph thiab chemoheterotroph Photoheterotrophs siv lub teeb lub zog rau lub zog tab sis xav tau cov organic teeb meem los ntawm cov pa roj carbon. Chemoheterotrophs tau txais lawv lub zog los ntawm cov tshuaj tiv thaiv tshuaj uas tso tawm lub zog los ntawm kev rhuav tshem cov organic molecules. Vim li no, ob qho tib si photoheterotrophic thiab chemoheterotrophic kab mob yuav tsum tau noj cov khoom muaj sia lossis tuag rau lub zog thiab nqa cov khoom organic.

Nyob hauv luv luv, qhov sib txawv ntawm autotrophs thiab heterotrophs nyob hauv qhov chaw lawv siv kom tau zaub mov.

Piv txwv autotrophic nyob creatures

  • The green nroj tsuag and algae yog autotrophic beings par excellence, tshwj xeeb yog photoautotrophs, siv lub teeb ua lub zog. Cov kab mob no yog qhov tseem ceeb rau cov khoom noj ntawm txhua lub ntiaj teb ecosystems.
  • Iron bacteria: lawv yog chemoautotrophs, lawv tau txais lub zog thiab zaub mov los ntawm inorganic tshuaj uas muaj nyob rau hauv lawv ib puag ncig. Peb tuaj yeem pom cov kab mob no hauv cov av thiab cov dej ntws uas muaj hlau ntau.
  • kab mob Sulfur: chemoautotrophs, lawv nyob rau hauv tsub zuj zuj ntawm pyrite, uas yog ib tug ntxhia ua los ntawm sulfur, uas lawv pub.

Piv txwv ntawm heterotrophic nyob beings

  • carnivores yog tag nrho cov heterotrophs vim lawv noj rau lwm yam tsiaj thiab nroj tsuag.
  • Fungi and protozoa: nqus cov organic carbon los ntawm lawv ib puag ncig. Lawv yog chemoheterotrophs.
  • Purple non-sulfur bacteria: yog photoheterotrophs uas siv non-sulfur organic acids rau lub zog, tab sis tau carbon los ntawm cov organic teeb meem.
  • Heliobacteria: lwm yam photoheterotrophs uas xav tau cov organic carbon nyob rau hauv cov av, tshwj xeeb tshaj yog nyob rau hauv cov qoob loo.
  • Manganese Oxidizing Bacteria: Ib qho chemoheterotroph uas siv cov pob zeb lava rau lub zog, tab sis tso siab rau nws ib puag ncig rau carbon organic.
