Detailed explanation-1: -Photoautotrophs, such as plants, use energy from sunlight to make organic compounds-sugars-out of carbon dioxide in photosynthesis. Other examples of photoautotrophs include algae and cyanobacteria. Chemoautotrophs use energy from chemicals to build organic compounds out of carbon dioxide or similar molecules.

Detailed explanation-2: -Figure 1: Photosynthetic plants synthesize carbon-based energy molecules from the energy in sunlight. Consequently, they provide an abundance of energy for other organisms. Plants exist in a wide variety of shapes and sizes.

Detailed explanation-3: -Producers such as plants, algae, and cyanobacteria use the energy from sunlight to make organic matter from carbon dioxide and water. This establishes the beginning of energy flow through almost all food webs.

Detailed explanation-4: -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. Glucose is used by plants for energy and to make other substances like cellulose and starch.
