NEED THIS ANSWERED AS SOON AS POSSIBLE!! What would happen if the photosynthesis and cell respiration didn't perform their roles in the carbon cycle? What would be a possible solution to the problem(s) that would arise?

While photosynthesis requires carbon dioxide and releases oxygen, cellular respiration requires oxygen and releases carbon dioxide. ... Without oxygen, much less ATP would be produced. Cellular respiration and photosynthesis are important parts of the carbon cycle.Without photosynthesis, there would be no sugar, without which there could be no cellular respiration. ... Both animal cells and plant cells depend on cellular respiration for their energy needs, because both animal cells and plant cells need ATP.

where is the diagram?

if you insert the diagram ill be able to you
