Members don't see this ad.

use modern theory of evo and order these:
krebs
anaerobic respiration
autotrophic nutrition
photosynthesis
chemosynthesis

i think i'm just getting the facts mixed up but its' anaerobic respiration of heterotrophs first.

this is true cuz is it just that anerobic heterotroph respiration is FIRST before everything? Nothing else came before it?

I'd imagine chemosynthesis would come before* anaerobic respiration because it can use inorganic molecules that were found in early earth's reducing atmosphere as energy. Anerobic respiration probably came after that.

 

[shoombol tallah]

The earliest were anaerobic heterotrophic prokaryotes followed by chemosynthetic prokaryotes.

yea kaplan says Anerobic respiration is first before the rest. i was just wondering if there is anything before this (that wasn't on the list of stuff from my original post) or does anyone know a good summary of evolution like that includes everything in order from rna polymers to anerobic resp.?
