Detailed explanation-1: -3.1 The Sun is the major source of energy for organisms and the ecosystems of which they are a part. 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-2: -During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen.
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: -The answer is photosynthesis. Photosynthesis is the ultimate source of nearly all energy used in all living organisms. This process is carried out by plants, algae, and bacteria to transform the energy of sunlight into chemical energy that can be stored and used by them and other organisms.
