What is the main source of energy for the process of photosynthesis?

The main source of energy for the process of photosynthesis is sunlight. During photosynthesis, plants capture sunlight through a pigment called chlorophyll located in their leaves. This light energy is then used to convert carbon dioxide from the air and water from the soil into glucose, a form of sugar that serves as food for the plant. Additionally, oxygen is released as a byproduct of this process.

Sunlight provides the necessary energy to drive the chemical reactions involved in the synthesis of glucose, making it an essential component of photosynthesis. Without adequate sunlight, plants would not have the energy required to produce their own food, which would ultimately affect their growth and survival. Other options like water, soil nutrients, and carbon dioxide are important materials used in photosynthesis, but they do not provide the energy required for the process.
