Herbivores are the dominant species on Earth so plants are the major source of energy next to an Omnivores diet of meat and plants. The plant process is photosynthesis and that's where the energy for an ecosystem comes from.
To sum up, the sun is the source of energy for the majority of ecosystems as sunlight is required for photosynthesis.
The sun.
Without the sun life on earth would soon stop because all available carbon (the basis of all life forms on Earth) would be used up.
A few ecosystems get their energy partially or entirely from geothermal sources. The original source of this energy is radioactive decay heat from isotopes in the crust, mantle, and core.
Both the sun and earth were formed from matter ejected and/or compressed by supernova explosions. So the original source for both the energy from the sun and from radioactive decay heat was supernovas.
Ultimately the original source of all energy was the Big Bang.
The sun is the original source of energy. The sun provides energy to all of the planets, especially to solar powered objects.
The sun or solar energy is at the start of almost every energy chain.

A prairie and a desert are different biomes and very distinct from each other. However, the primary source of energy in almost any ecosystem is the sun.
The most important source off all is WATER!
The main source of energy is usually considered to be the energy absorbed from the sun (E.G., used in photosynthesis).
The sun is the ultimate source of energy for almost all earth ecosystems.
The primary source of energy for almost all food chains is the sun. The usual series is that the sun provides energy to plants that provide to other creatures. Some ecosystems rely on other energy sources however. For instance some deep ocean ecosystems rely on geothermal energy harvested by bacteria.
The Sun is the primary source of all energy in nearly all food chains. However, some deep-sea ecosystems utilize heat from underwater thermal vents as their primary energy sources since sunlight is virtually nonexistent.
The sun Added: This is definitely true. Sunlight affects all surface and shallow water ecosystems. All though the sun provides us with a primary source of energy for almost all of earth's ecosystems, with proof of greenery from photosynthesis; this is not the case in such areas like the land of the Sahara desert and the Southwest climates of the USA. The lack of abundant water is another factor.
