Cereal plants gain chemical potential energy as they grow. which form of energy is converted to create the chemical potential energy?

The plant absorbs the sunlight which serves as source of energy for the plant. Therefore, the form of energy which gets converted to “chemical potential energy is the solar energy”.

Explanation:

In process of photosynthesis, the plant makes the food and release oxygen, this occurs only in presence of solar energy that is sunlight. Therefore, the source of energy for the plants are sunlight which provides solar energy which is used up in energy conversion through various process.

The end product of the energy resource is the conversion to chemical potential energy gained over the growth of the cereal plants.
