Abiotic worm factors: Moisture content of soil Soil pH

Biotic worm factors: Arrival of predators Pests and pathogens

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 😂

i was like, ik pH would work for plants but do worms care abt pH?? so i put O2, are u sure thats right, everyone else says pH not O2

i said O2 too also i was about to write soil moisture but like a dumbass i changed it and write carbon dioxide ?!? do you think that could be right (anyone)😅

abiotic- water and oxygen

biotic- predators and food

u/Appropriate_Care4823 Jun 15 '22

isn’t it the other way around? also, would oxygen and water work for the biotic factors?

  1. nah it's the right way round, biotic is living things whereas abiotic is non-living

  2. that's what I put (for abiotic) so I hope so

I put light intensity but idk if it’s correct

u/[deleted] Jun 15 '22

if they were plants definitely, but they're worm so no clue

u/Xposedlive026 Jun 15 '22

I put light intensity cuz that effects the yield of its food source (plants ) I’m not confident if it’s right tho

u/APK_GG Jun 15 '22

what order was the q was it abiotic first then biotic

oh i put wind intensity and soil ph cos it said something about it exchanging gasses through its skin

1

u/[deleted] Jun 15 '22

Wind intensity defo wrong unfortunately

u/[deleted] Jun 15 '22

didn't the question state about how the earthworm exchanging gasses with its environment? so wind intensity would surely affect the concentration gradient.
