What evidence supports the law of conservation of energy?

Mechanical energy is converted to chemical energy during photosynthesis.
Oxygen is made from the breakdown of carbon dioxide during photosynthesis.
Energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis.
The sun gives off light energy that is absorbed by plants.

Respuesta :

The right answer is C

I will explain the law of conservation of energy by photosynthesis:

The conservation principle states that the energy of an isolated system (chlorophyll) can not vary.

On the other hand, if the system is not isolated (it is in the nature, exposed to the sun), that is to say if it can exchange with the outside, (the chlorophyll will absorb the photons put by the Sun). Thus the system transforms this absorbed energy into another form (glucose in the case of photosynthesis).

The first law of thermodynamics states that energy is conserved and cannot be created or destroyed. The process of photosynthesis also follows the law of conservation of energy.

The correct answer is:

Option C: Energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis.

Photosynthesis is the process of making own food in the presence of sunlight, carbon dioxide, and water.  The leaves are the primary site for photosynthesis, as they consist of chlorophyll.

Chlorophyll is a green color pigment that captures light energy and stores them in the form of chemical energy as bonds. These bonds when broken down yield energy that is used up by plants to perform various activities.

Therefore, the energy absorbed by the plants is used to make glucose, which is then converted into chemical energy.
