Sun and Food ( that includes water)
The energy sources that I am most excited about all have lower carbon emissions, compared to conventional energy sources. These include Biomass Energy, Wind Energy, Solar Energy, Geothermal Energy, and Hydroelectric Energy sources.
Most life on earth, gets there energy source from the sun, that is assuming that the majority of life on earth are autotrophs (plants). They get this energy by photosynthesising and getting a energy source called glucose, which is used in nearly all organisms on earth... they can then use glucose as a respiratory substrate, for respiration... Hope this helps :)
The sun is the source of most of the energy on Earth. Oceans come second.
With few exceptions, the origin from which all organisms on earth get their energy is the sun.
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.
The sun is the primary source of energy for the Earth, providing sunlight that powers photosynthesis in plants, which in turn fuels most life on the planet. Other sources of energy on Earth include geothermal energy, tidal energy, and the Earth's internal heat.
The primary source of energy on Earth is the sun. Solar energy powers various processes on Earth, including photosynthesis in plants, which in turn sustains all forms of life on the planet. Additionally, other sources of energy on Earth, such as geothermal energy and fossil fuels, are derived from the sun's energy in one way or another.
The energy on Earth comes from various sources, including the Sun, which provides solar energy through sunlight. Geothermal energy from the Earth's core also contributes to the energy available on Earth. Other sources include nuclear energy from radioactive decay and gravitational energy.
The energy from the Sun, solar energy drives all the process important to life on Earth.
Solar energy drives all the processes important to life on Earth.
The primary energy source for life on Earth is the sun. Through the process of photosynthesis, plants convert sunlight into chemical energy that is then used by plants and ultimately other organisms for survival and reproduction.
