In photosynthesis, light energy is converted into chemical energy plus heat energy. According to the first law of thermodynamics,
A) the amount light energy is greater than the amount of chemical energy and heat energy combined.
B) the amount of energy in heat plus chemical energy is greater than the amount of energy in light.
C) the amount of light energy is equal to the amount of chemical energy and heat energy combined.
D) the amount of light energy is equal to the amount of chemical energy, since both are forms of potential energy.
E) there is no relationship between the amount of energy in light versus the amount of energy in chemical and heat energy since they are all different forms of energy.

Question

Quizplus · Accepted Answer

The first law of thermodynamics, also known as the law of energy conservation, states that energy cannot be created or destroyed in an isolated system. Therefore, the amount of light energy absorbed during photosynthesis must be equal to the sum of the chemical energy stored and the heat energy released.
