How do photosynthesis and respiration affect the carbon- oxygen cycle?

Answer 1

respiration is a biophysical process of human biophysical this process oxygen is inhaled and carbon-dioxide is exhaled. Exhaled carbon-dioxide is consumed by plants to photosynthesise and and oxygen that is released by plants are taken by us.photosynthesis and respiration maintains carbon oxygen cycle.

Answer 3

see its very easy.first as you know photosyntheesis is done by plant s and respirstion takes place due to animals(humans).

for respration human or animal needs glucose and O2 and when glucose and oxygen react with each other so energy,water and CO2{reason ofthe intake of O2 but exhale of CO2}

but before i go on u would be thinking that where does the oxygen and glucose comes from

they come from plants through photosynthesis means plants need CO2, water and energy for photosynthesis and when these things react with each other so they produce oxygen and glucose

it means both process are connected to each other what is made from photosynthesis is used by respiration and things made by respiration are used by photosynthesis.

{i know i have went in a big big detail u asked for O2 and CO2and i told whole story but still i hope u will find it helpful just remember both things are joined with each other if plants rae not there so no photosynthesis and if no humans or animals so no respiration.}
