Here's why:
* Solar Energy: Plants absorb sunlight, the primary source of solar energy.
* Chemical Energy: Plants use this light energy to convert carbon dioxide and water into glucose (a sugar), storing the energy in the chemical bonds of the glucose molecule. This glucose is a form of chemical energy that the plant can use for growth and other processes.
In short: Photosynthesis is the process of converting light energy from the sun into chemical energy in the form of glucose, which plants use as fuel.
