Detailed explanation-1: -Most autotrophs use a process called photosynthesis to make their food. In photosynthesis, autotrophs use energy from the sun to convert water from the soil and carbon dioxide from the air into a nutrient called glucose. Glucose is a type of sugar. The glucose gives plants energy.
Detailed explanation-2: -The process is carried out by plants, algae, and some types of bacteria, which capture energy from sunlight to produce oxygen (O2) and chemical energy stored in glucose (a sugar). Herbivores then obtain this energy by eating plants, and carnivores obtain it by eating herbivores.
Detailed explanation-3: -Not only carbohydrates, as was once thought, but also amino acids, proteins, lipids (or fats), pigments, and other organic components of green tissues are synthesized during photosynthesis.
Detailed explanation-4: -An autotroph is an organism that produces complex organic compounds (such as carbohydrates, fats, and proteins) using carbon from simple substances such as carbon dioxide, generally using energy from light (photosynthesis) or inorganic chemical reactions (chemosynthesis).
Detailed explanation-5: -Carbohydrates can be used as an immediate source of energy by largely all cells, but in many photosynthetic organisms a major portion of the carbohydrates will be used for production of structural compounds, e.g., cellulose in cells walls, or for synthesis of storage products such as starch.
