The equator gets the most radiant sunlight on Earth.
It isn't clear what "spheres" you are talking about, but the Earth in general gets most of its energy from sunlight.
The Earth gets most of its energy from the Sun.
Energy that water gets from the sun is most commonly absorbed in the form of heat.
Most of the light's energy gets converted into heat.
Earth has internal energy due to radioactivity. I am not sure what you mean by radioactive external energy, or simply by external energy. Earth gets most of its energy from the Sun.
The herbivores obtain most of their energy in the form of food from plants.
Wind energy, solar power and hydrolicpower
Heat.
None of those is really a "source" of energy; those are only ways in which energy is transported. Earth gets most of its energy from the Sun, through radiation.
Some gets absorbed and converted into other energy forms. Most of the energy will eventually get radiated back into space.
