Question

Photosynthetic organisms produce sugar molecules from radiant energy and inorganic substances. These sugar molecules are then used to provide energy so the organisms can grow and move. Which energy transformation occurs in the second step of this process?
A.) Chemical energy to mechanical energy
B.) mechanical energy to radiant energy
C.) radiant energy to mechanical energy
D.) mechanical energy to chemical energy.

Answer 1

The answer is A. 

Chemical (in this case, sugar) to mechanical (enables organisms to move, etc).

I tried to explain it as simple as possible.

Hope it helped!

Answer 2

The right answer is A.) Chemical energy to mechanical energy.

In this situation, the energy of radiation represents the sun, the chemical energy represents the molecule of glucose, and finally, the mechanical energy represents the functioning and survival of the living organisms.

In the second process, which is respiration, there is a transformation of glucose into directly exploitable energy. and therefore from a chemical energy to a mechanical energy.
