What is the main difference between aerobic respiration and anaerobic respiration? a)aerobic respiration requires oxygen to proceed, but anaerobic respiration does not. b)aerobic respiration occurs during photosynthesis, but anaerobic respiration occurs during cellular respiration. c)aerobic respiration produces atp, but anaerobic respiration does not. d)aerobic respiration occurs only in living organisms, but anaerobic respiration occurs in nonliving organisms.

Aero- Air  Ana- Non 

Aerobic is respiration and Anaerobic is something that doesn't require Oxygen.

D) Is Obviously, wrong  due to the fact that nonliving organisms don't even do any type of process 

C) This is true because, in photosynthesis is water, glucose and energy but, even though there is no oxygen still this is used because, Of cellular respiration because, these two cycle with each other and in order to keep this cycle as a 'cycle' it needs to produce ATP. (In this case it makes 2 ATP (( Cellular respiration)) 
B) is correct In it way that Photosynthesis takes in light and, needs Oxygen to turn into Carbon. And Anaerobic respiration which is Cellular respiration. 

A) Is is right as well, which seems wrong because, it's obvious but the word even proves it (i.e- the definition above) 

A) is he correct answer.
