Answer:

When sodium bicarbonate is added to the water, the bicarbonate ion acts as a carbon source for photosynthesis causing the leaf disks to sink. As photosynthesis proceeds, oxygen is released into the interior of the leaf, which changes its buoyancy causing the disk to rise.

How are the processes of photosynthesis and respiration related to one another?
Leokris [45]

<u>Answer:</u>

Photosynthesis and respiration are so interrelated with each other that one’s product are used as another’s reactant.

<u>Explanation:</u>

  • Photosynthesis is a process used by organisms to convert 'light energy' into 'chemical energy', which is used as a source of energy for the organism.
  • Respiration is a process in which glucose and oxygen is used to create ATP for the survival of the organism.
  • During photosynthesis 'water and carbon dioxide' reacts in presence of light to create oxygen and glucose.
  • Without photosynthesis and respiration life ceases to exist on earth.
