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

LAW OF CONSERVATION OF ENERGY:The law of conservation of energy states that energy can neither be created nor destroyed but is changed from one form to another. This means that energy involved in chemical reactions and natural phenomena is recycled by transformation and doesn't get destroyed. A typical example that obeys this law is photosynthesis, which converts mechanical energy in sugar molecules to chemical energy in ATP.

Answer from: 1tallison1

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 the universe there is a constant amount of matter and energy, which is neither created nor destroyed, but transformed.Energy in an isolated system does not vary, unless it comes into contact with another system.The amount of energy that is absorbed and obtained is equivalent.

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.
