Historically, it was the Sun, which created the plant life and animal life used to make energy, and which formed fossil fuels. Even hydroelectric energy is dependent on solar heating to return water to its sources.
And because we now have nuclear energy, the answer could be "from nuclear reactions" -- fusion on the Sun and fission in nuclear generators.
This, however, neglects the use of tidal energy and geothermal energy. Tidal energy is caused primarily by the gravitation of the Earth and Moon, not the Sun. And geothermal energy is drawn from magma formed by crustal movements, which ultimately are driven by the Earth's hot core. The heat there is a combination of radioactive heat, tidal heat from the Sun's gravity, and energy left from the formation of the planet.
The ultimate source, therefore would have to be "gravity" because it formed the Sun and planets, keeps fusion going, moves the tides, and keeps the Earth's core hot enough to produce tectonics.
There is no true root of energy. Energy is neither created nor destroyed. The source of energy on Earth, however, is the sun.
the sun
A plant get it's food from it root. It's roots absorbs all the nutrients from the ground. by the roots and stem.
The s orbital has the lowest energy level.
all living things use energy
Kinetic energy
Solar energy
false
in the roots
Chipmunks get energy from the nuts, seeds, and roots that they eat.
All their living energy draws down into their roots. Spring thaw brings it all back.
Plants receives some important nutrients from their roots, that can give them enough for their reproduction and the energy that they need.
they grow shallow roots and (I think...) they store as much energy as they can. If you have a complaint, :P
The sun's energy. Through the roots and leaves.
It's used in the stem, roots, and leaves.
Storage roots are those roots which store a portion of the energy/nutrients gathered or produced by a plant, Potatoes , beets , ginger are some examples of them.
Nutrients from its roots then it just recycles the energy it gets from photosynthesis
-39 has no rational roots.
All numbers have cube roots (not necessarily integral cube roots) so every prime has cube roots.
