Why is the sun the main source?

Answer 1

The sun is the source of energy for everything basically because it gives off sunlight, which almost everything needs, and also because plants need sunlight to get food, (and in the energy pyramid producers are at the bottom, which leads to everything as in secondary consumers, primary consumers, teritari consumers and decomposers, so without producers, there wouldn't be any secondary consumers (because they wouldn't have food) and without secondary consumers there wouldn't be any primary consumers out of starvation, etc. Hope you understand now.

Alao, every source of energy is derived from solar energy. The exceptions include; geothermal energy, nuclear energy, tidal energy, and some chemical reactions. But petroleum is stored sunlight, as is wood and plant fiber. Wind energy is derived from the heating of the atmosphere by the Sun, and hydroelectric energy is dependent upon evaporation of sea water by the Sun.

The Sun produces a huge amount of energy, of which the Earth intercepts only a tiny fraction.
