Final answer:

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transferred or transformed. There is evidence to support this law in photosynthesis, where mechanical and light energy are converted into chemical energy in plants.

Step-by-step explanation:

The Law of Conservation of Energy states that energy cannot be created or destroyed, only transferred or transformed. There is evidence to support this law in the process of photosynthesis in plants. During photosynthesis, light energy from the sun is converted into chemical energy in the form of glucose and other carbohydrates. This energy is then stored in the chemical bonds of these molecules.

Examples of the evidence supporting the Law of Conservation of Energy in photosynthesis include:

  1. 1. Mechanical energy from the sun is converted into chemical energy in the process of photosynthesis.
  2. 2. Energy is absorbed by chlorophyll and converted into chemical energy during photosynthesis.
  3. 3. Oxygen is produced as a byproduct of breaking down carbon dioxide during photosynthesis.
  4. 4. The sun gives off light energy which is absorbed by plants and converted into chemical energy through photosynthesis.
