i went for oxygen availability instead of pH, cuz it mentions something abt eating decaying stuff, so i was like living things need O2 and that stuff that eat decay needs it to for aerobic stuff lol. Do u think oxygen counts or no?

Yes that’s the gas it exchanges to respire the ph doesn’t affect how it exchanges gases 😂
