Detailed explanation-1: -It radiates light and heat, or solar energy, which makes it possible for life to exist on Earth. Plants need sunlight to grow. Animals, including humans, need plants for food and the oxygen they produce. Without heat from the sun, Earth would freeze.
Detailed explanation-2: -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-3: -The ultimate source of all energy is the sun. Plants get the energy to prepare their food from the sun and that is transferred to the whole food chain.
