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. These primary producers form the base of an ecosystem and fuel the next trophic levels.

Detailed explanation-2: -Green plants produce their own food with the help of sunlight, chlorophyll, water, nutrients from soil, and carbon dioxide from the air. This process is called photosynthesis.

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.
