What evidence supports the LAW OF CONSERVATION OF ENERGY? 1. Mechanical energy is converted to chemical energy during photosynthesis
2. Energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis
3. Oxygen is made from the breakdown of carbon dioxide during photosynthesis
4. The sun gives off light energy that is absorbed by plants

The evidence that supports the law of conservation of energy is as follows: mechanical energy is converted to chemical energy during photosynthesis.

Taking into account photosynthesis, the evidence that best supports the law of energy conservation is energy is absorbed by chlorophyll and becomes chemical energy during photosynthesis (option 2).

Explanation:

Plants are autotrophic organisms, characterized by synthesizing their own nutrients by converting solar energy into chemical energy through photosynthesis.

During the process of photosynthesis, chloroplasts are capable of absorbing solar energy and converting it into glucose. This process involves the conversion of one type of energy into another.

With respect to the law of conservation of energy, it is necessary to consider:

In photosynthesis, the chloroplast is not an isolated system, but has contact with the outside and is capable of absorbing the energy of the sun. This energy will be used to obtain a product, glucose, in an amount proportional to the amount of energy absorbed.

Regarding other options:

    1. In photosynthesis, it is not mechanical energy that is transformed into chemical energy.

    3. Oxygen is a product of photosynthesis, during the process of chemical energy synthesis, from the combination of carbon dioxide, water and solar energy.

    4. It is true that the sun gives off light energy that is absorbed by plants, but it does not explain how this energy is transformed into chemical energy.
