The most important source off all is WATER!
The sun is the ultimate source of energy for almost all earth ecosystems.

The primary source of energy that flows through most living systems is glucose and carbohydrates. These energy sources are easy to produce and find.
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 main source of energy for most ecosystems is the sun. Through the process of photosynthesis, plants and other photosynthetic organisms convert sunlight into chemical energy that fuels the ecosystem. This energy is then passed along the food chain as organisms consume each other.

The Sun
The ultimate source of energy for nearly all surface terrestrial and shallow water ecosystems is the sun. Through the process of photosynthesis, plants and other autotrophs convert sunlight into chemical energy that is then passed on to other organisms in the ecosystem.

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.
