Sunlight also gets reflected back out into space.
sunlight
All the energy for living things and all the energy for fossil fuel, hydroelectric and wind energy comes form the energy of sunlight. Without sunlight there would be no life and Earth would be a frozen dead planet.
sunlight
All living things on Earth derive their energy ultimately from the sun. Through the process of photosynthesis, plants convert sunlight into chemical energy, which is then passed on through the food chain. In this way, sunlight is the primary source of energy for most life forms on Earth.
energy source for all life on earth
"The energy used by all organisms on earth" Cannot be traced back to sunlight.Although until recently sunlight was thought to be the energy source responsible for all life on earth, we now know that there is life that does not rely on sunlight. At the bottom of the ocean for example, there is life that relies on chemosysthesis - a process of converting "chemicals" to energy that does not require any sunlight. .http://en.wikipedia.org/wiki/Chemosynthesis.Hope that helps.

In that case, plants - and with them, all life on Earth - would die.
Sunlight is essential for photosynthesis, the process by which plants convert sunlight into energy in the form of glucose. This energy is then passed on to other living things through the food chain. Additionally, sunlight helps regulate natural processes such as temperature, weather patterns, and the water cycle, all of which support life on Earth.
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 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 sun is considered the source of almost all energy on Earth because it emits vast amounts of energy in the form of sunlight. This sunlight is essential for processes like photosynthesis in plants, which creates food and energy for all living organisms. Additionally, solar energy powers weather patterns, ocean currents, and other natural processes that drive the Earth's systems.
