Which of the following shows the change in energy carrying molecules as a system moves through photosynthesis and cellular respiration?

water (liquid energy) to oxygen (chemical energy) to atp (chemical energy)

light energy to oxygen (chemical energy) to atp (chemical energy)

light energy to glucose (chemical energy) to atp (chemical energy)

none of the above

The correct option is A. Water (liquid energy) to oxygen (chemical energy) to ATP (chemical energy)

Explanation:

Photosynthesis can be described as a process by which plants use light energy to convert water and carbon dioxide into glucose and oxygen. Oxygen is produced as a by-product for this reaction.

In the reaction of photosynthesis, water releases it's oxygen atom. 6 oxygen atoms are produced as the result of photosynthesis. The oxygen and glucose are used by the cells to carry out cellular respiration and generate ATP. Hence, A is the correct option.

As light energy doesn't change in this reaction, hence options B and C are false.

c should be the answer

when it is at an intermediate population density
