This process, called photosynthesis, is essential to the global carbon cycle and organisms that conduct photosynthesis represent the lowest level in most food chains (Figure 1). Most living things ...

Be careful not to confuse this photosynthesis equation with respiration which is the reverse of this. The balanced symbol equation shown above is Higher tier only.

During the light, provided the rate of photosynthesis is sufficiently high, plants, give out oxygen. The overall reaction for photosynthesis as given above is a simplification. Photosynthesis ...
