Indication on how cellular respiration & photosynthesis form interdependent cycle

I reaaally need to know this): Any type of help appreciated! Best answer should be easy for this one. Just give me a few points on how they are related as an interdependent cycle aka for cellular respiration and photosythesis.
THANK YOU!! :)
Also, do you know specifics for one type of anaerobic respiration, include uses for food products?

photosynthesis - carbon dioxide + water ---> sugar + oxygen
respiration - sugar + oxygen ---> carbon dioxide + water

if you dont have oxygen, no respiration, to get oxygen, you need photosynthesis, so respiration is dependent on photosynthesis

Also, if you dont water/carbon dioxide, no photosynthesis, you need respiration to produce water and carbon dioxide and so photosynthesis is dependent on respiration

aneorobic respiratio - yeast - why does batter/bread dough rise with yeast in it? because yeast respires and produces carbon dioxide.
