The food organisms eat is the source of most energy for life.
Autotrophs are living beings that "make their own food". Those are plants, and algae. Those get their energy from the sunlight.
Heterotrophs (animals, and others) get their energy from other living beings. They use the chemical energy from those other living beings.

The most reliable source of energy for life on Earth is the Sun. Solar energy provides the necessary light and heat for photosynthesis, which is the process by which plants and other organisms convert sunlight into energy. This energy powers most ecosystems and is essential for sustaining life on our planet.
The fundamental source of energy on Earth is the sun. Solar energy is the primary driver of most natural processes and life on our planet.
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 energy source for most life on Earth is the sun, because the sun makes plants grow and animals eat the plants.
Sunlight is the main energy source for life on earth.
Sunlight is the most important energy source in an oxygen carbon dioxide life cycle.
