The energy in most ecosystems comes from the sun through a process called photosynthesis. Plants, algae, and some bacteria convert sunlight into chemical energy in the form of glucose, which is then transferred to other organisms through the food chain.
The most important transformers of energy in ecosystems are producers (such as plants) that convert sunlight into chemical energy through photosynthesis, and decomposers (such as bacteria and fungi) that break down organic matter into simpler compounds and release nutrients back into the ecosystem. These transformers play crucial roles in the flow of energy through the food chain.
At the base of nearly every ecosystem on Earth is the energy from sunlight. There are rare examples in the abyssal plains/trenches where chemosynthesis takes place due to internal heat and exhaust from the asthenosphere/magma layer. However, since most ecosystems include photosynthetic plants, the energy from sunlight forms the basis for most energy in the system.
Most of the cranial nerves originate from the brainstem.
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.

The main fate of energy is for it to be lost as heat.

The energy first comes from the sunlight, then the producers (green plants) absorb the energy. Sunlight
We concentrate on glucose breakdown, since it dominates energy production in most animal cells.
On earth, most forms of energy ultimately originate from the sun. Even fossil fuels are just decomposed plant matter, which also gained energy from the sun. Alternately, other sources include nuclear, hydroelectric and geothermal sources.

The sun is the ultimate source of energy for almost all earth ecosystems.
The energy source of all ecosystems is sunlight. Sunlight is captured by plants through photosynthesis, which converts it into chemical energy that is then passed on to other organisms through the food chain.
