kwj ecosystems tau txais lub zog los ntawm ob qhov chaw: allochthonous inputs, uas muaj ntawm cov pa roj carbon monoxide (C) uas tau tsim nyob rau hauv qhov dej ntws thiab tuaj rau hauv kwj channel (piv txwv li, Kaushik & Hynes, 1971), thiab autochthonous ntau lawm, uas suav nrog C tsau nyob rau hauv cov kwj channel los ntawm algae thiab …
autochthonous input yog dab tsi?
Hauv cov dej hauv cov zej zog, cov tswv yim autochthonous yog muab los ntawm photosynthesis ntawm cov nroj tsuag loj thiab txuas algaehauv cov dej ntiav (littoral zone) thiab los ntawm microscopic phytoplankton.

Qhov txawv ntawm autochthonous thiab allochthonous inputs yog dab tsi?
Nyob hauv ecology cov ntsiab lus kuj tseem siv tau thaum xa mus rau ntau qhov chaw ntawm cov organic carbon, feem ntau hauv cov pas dej uas cov khoom loj yog ib qhov chaw (autochthonous) thiab cov organic carbon uas tau ntxuav rau hauv lub pas dej los ntawm cov kwj deg yog lwm qhov (allochthonous).
