Qhov Tseem Ceeb Qhov txawv - Phototrophs vs Chemotrophs
Cov kab mob yog categorized raws li kev noj haus. Qee cov kab mob muaj peev xwm tsim tau lawv cov zaub mov thaum qee cov kab mob nyob ntawm lwm yam khoom noj uas tsim los ntawm lwm cov kab mob. Qee cov kab mob qhia kev sib txawv kom tau txais cov khoom noj. Yog li ntawd, ntau hom kab mob muaj nyob, thiab ntawm lawv, phototrophs thiab chemotrophs yog ob pawg tseem ceeb. Phototrophs yog cov kab mob uas siv lub hnub ci los ua lawv lub zog los ua haujlwm ntawm tes. Muaj ob hom phototrophs; photoautotrophs thiab photoheterotrophs. Chemotrophs yog cov kab mob uas nyob ntawm lub zog tsim los ntawm oxidation ntawm inorganic lossis organic molecules. Chemotrophs yog ob hom tseem ceeb xws li chemoautotrophs thiab chemoheterotrophs. Qhov sib txawv tseem ceeb ntawm phototrophs thiab heterotrophs yog lub zog uas lawv siv. Phototrophs cia siab rau lub hnub ci kom tau txais lub zog thaum chemotrophs tsis cia siab rau lub hnub ci kom tau txais lub zog es tsis txhob cia siab rau cov tshuaj rau kev tsim hluav taws xob.
Phototrophs yog dab tsi?
Phototrophs yog pab pawg ntawm cov kab mob uas siv lub zog los ntawm lub hnub ci los tsim ATP los ua haujlwm ntawm tes. Hauv lwm lo lus, phototrophs yog cov kab mob uas tso siab rau lub hnub ci los tsim lawv tus kheej cov zaub mov lossis oxidize organic molecules los tsim lub zog rau kev ua haujlwm ntawm tes. Lub npe "Photo" yog hais txog lub teeb, thiab lo lus "trophs" yog hais txog txoj kev tau txais zaub mov los yog khoom noj. Yog li ntawd, phototrophs yog cov kab mob uas ua tiav lawv cov khoom noj khoom haus uas siv lub hnub ci.
Muaj ob hom phototrophs uas yog photoautotrophs thiab photoheterotrophs. Photoautotrophs tuaj yeem txhais tau tias yog cov kab mob uas ua rau lawv tus kheej cov khoom noj los ntawm kev siv lub hnub ci thiab cov pa roj carbon inorganic uas yog carbon dioxide. Cov txheej txheem lawv ua yog photosynthesis. Lawv muaj cov organelle tshwj xeeb thiab cov xim kom ntes lub zog ntawm lub hnub ci thiab siv nws los tsim cov organic molecules los ntawm carbon dioxide thiab dej. Piv txwv ntawm cov kab mob photoautotrophic yog cov nroj tsuag ntsuab, algae, cov kab mob photosynthetic, cyanobacteria, thiab lwm yam. Tag nrho cov nroj tsuag ntsuab feem ntau yog photosynthetic. Lawv ua hauj lwm ua ib qho khoom noj tseem ceeb rau thaj av ecosystems. Photoautotrophs yog qhov tseem ceeb heev rau kev noj qab haus huv ntawm feem ntau ntawm cov ecosystems thiab kev ciaj sia ntawm heterotrophs. Heterotrophs nyob ntawm seb cov khoom noj uas tsim los ntawm autotrophs. Thiab tseem phototrophs tseem ceeb heev txij li thaum lawv muaj peev xwm tshem tawm cov pa roj carbon dioxide los ntawm huab cua thiab tso pa oxygen rau cov huab cua ntawm cov tsiaj ua pa.
Daim duab 01: Phototroph – Ntsuab Nroj Tsuag
Photoheterotrophs yog cov kab mob uas ua rau lub zog ntawm lub hnub ci thiab siv cov khoom siv organic ua lawv qhov chaw carbon. Lawv tsis yog photosynthetic, thiab lawv tsis tuaj yeem siv carbon dioxide. Hloov chaw, lawv siv cov organic carbon cov khoom tsim los ntawm lwm yam kab mob. Photoheterotrophs tsim ATP los ntawm cov txheej txheem hu ua photophosphorylation.
Chemotrophs yog dab tsi?
Chemotrophs yog cov kab mob uas tau txais lub zog los ntawm cov tshuaj oxidation los yog chemosynthesis. Lawv tsis tuaj yeem siv lub hnub ci ua lawv lub zog. Hloov chaw, lawv siv inorganic lossis organic compounds thiab tau txais lub zog los ntawm oxidation. Lub npe "chemo" yog hais txog cov tshuaj thiab lo lus "troph" yog hais txog cov khoom noj. Li no, cov kab mob no yog nyob ntawm cov tshuaj rau lub zog.
Chemotrophs tuaj yeem yog ob pawg uas yog chemoautotrophs lossis chemoheterotrophs. Chemoautotrophs muaj peev xwm tsim lawv tus kheej cov khoom noj los ntawm chemosynthesis. Lawv siv cov tshuaj inorganic xws li H2S, NH4+, Fe2+ as txo cov neeg ua haujlwm thiab tsim cov carbohydrates los ntawm carbon dioxide. Cov kab mob no muaj nyob rau hauv ib puag ncig huab xws li dej hiav txwv tob, thiab lwm yam. qhov chaw tshav ntuj tsis tuaj yeem ncav cuag. Piv txwv ntawm chemoautotrophs muaj xws li methanogens, halophiles, nitrifiers, thermoacidophiles, sulfur oxidizers, thiab lwm yam.

Chemoheterotrophs yog cov kab mob uas nyob ntawm cov organic tebchaw rau lub zog thiab cov pa roj carbon. Cov kab mob no noj cov zaub mov xws li carbohydrates, lipids, proteins uas tsim los ntawm lwm yam kab mob. Chemoheterotrophs yog hom kab mob ntau tshaj plaws nrog rau feem ntau ntawm cov kab mob.
Dab tsi zoo sib xws ntawm Phototrophs thiab Chemotrophs?
- Ob lub phototrophs thiab chemotrophs yog pab pawg ntawm cov kab mob raws li hom khoom noj khoom haus.
- Ob pawg phototrophs thiab chemotrophs muaj xws li autotrophs thiab heterotrophs.
- Ob pawg phototrophs thiab chemotrophs tuaj yeem pom hauv tib ecosystems.

Summary – Phototrophs vs Chemotrophs
Phototrophs thiab chemotrophs yog ob pawg tseem ceeb ntawm cov kab mob uas raug cais raws li hom khoom noj khoom haus. Phototrophs ua lub zog rau lawv cov txheej txheem ntawm tes siv lub hnub ci (lub hnub ci zog). Chemotrophs tsis tuaj yeem siv lub hnub ci zog. Yog li lawv nyob ntawm lub zog tsim los ntawm chemosynthesis. Cov tshuaj yog oxidized los ntawm chemotrophs los tsim lub zog rau lawv cov cellular zog. Ob pawg suav nrog cov kab mob uas ua rau lawv tus kheej cov zaub mov thiab cov kab mob nyob ntawm cov khoom noj uas tsim los ntawm lwm cov kab mob. Chemotrophs yog hom kab mob ntau tshaj plaws. Phototrophs yog qhov tseem ceeb rau kev ua haujlwm ntawm ntau lub ecosystems. Photoautotrophs uptake carbon dioxide los ntawm huab cua thiab tso pa oxygen mus rau qhov chaw. Kev ciaj sia ntawm lwm cov kab mob heterotrophic yog nyob ntawm photoautotrophs. Qhov no yog qhov txawv ntawm phototrophs thiab chemotrophs.
