Detailed explanation-1: -Plants are autotrophs, which means they produce their own food. They use the process of photosynthesis to transform water, sunlight, and carbon dioxide into oxygen, and simple sugars that the plant uses as fuel.

Detailed explanation-2: -Photosynthesis: The plants produce their own food by a process called photosynthesis. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize food from carbon dioxide and water. Chlorophyll present in the chloroplast as a green pigment can trap the solar energy.

Detailed explanation-3: -Photosynthesis is a biological process used by plants to prepare their food with the help of sunlight and energy. This process occurs usually when plants use light energy to convert carbon dioxide and water into glucose and oxygen gas.
