How are photosynthesis and respiration considered to be paired in the carbon cycle?

Question

pls explain.i need to know for science. thank you! =]

Answer 1

They are opposite reactions.  Photosynthesis takes the carbon dioxide and converts it into sugar.  While doing this the process gives off oxygen into the atmosphere.  In respiration the process takes the sugar and uses it as an energy source, releasing carbon dioxide and using the oxygen.

Answer 2

7th/8th grade understanding

photosynthesis makes oxygen out of carbon, respiration takes oxygen to make carbon

so when respiration makes carbon>photosynthesis takes that carbon and make it into oxygen>then respiration takes that oxygen and releases carbon and it goes on and on

Answer 3

by my calculations i presume that photosynthesis is quite interesting indeed.
