Detailed explanation-1: -The sun is called the ultimate source of energy because: It is the primary source of energy for the earth. With the help of solar energy, all green plants(producers) produce food by the process of photosynthesis. In turn, animals eat plants and use that same chemical energy for all their activities.

Detailed explanation-2: -Energy Production In most ecosystems, the ultimate source of all energy is the sun.

Detailed explanation-3: -The sun is called the ultimate source of energy because it is the source of almost all energies of the earth. Plants convert light energy from the sun into chemical energy (food) by the process of photosynthesis.

Detailed explanation-4: -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-5: -The source of energy of the Sun is due to the conversion of hydrogen to helium. Solar energy is created as a result of a process known as Nuclear Fusion, a chain reaction that takes place in the Sun.
