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: -The characteristics of Photosynthesis include: It is a process that occurs solely in plants that have the green pigment chlorophyll used to prepare food. The requirements include Sunlight, water, and oxygen, where two processes occur one light-dependent and another which is light-independent.

Detailed explanation-3: -Plants use a process called photosynthesis to make food. During photosynthesis, plants trap light energy with their leaves. Plants use the energy of the sun to change water and carbon dioxide into a sugar called glucose.

Detailed explanation-4: -Photosynthesis is an example of a metabolic process with 2 stages. Both the stages need light (direct or indirect sunlight).

Detailed explanation-5: -Carbon dioxide is converted into sugars in a process called carbon fixation; photosynthesis captures energy from sunlight to convert carbon dioxide into carbohydrates. Carbon fixation is an endothermic redox reaction.
