What is the best source of energy for an ecosystem?

Answer 1

Sun is best source of energy in ecosystem , as the sunlight is essential part of photosynthesis , so the PRODUCERS (plants , algaee etc ) prepare their food from it ,which in turn helps in survival of ecosystems.

Answer 2

Depends upon the ecosystem. The vast majority of terrestrial (on land) and aquatic (in water) ecosystems on the Earth are fuelled by solar radiation. The producers in an ecosystem, plants, convert sunlight into chemical energy that other life forms can use when the plants are eaten. Sunlight doesn't directly reach some ecosystems, like ones found in ocean trenches thousands of kilometres below the surface of the ocean; these are fuelled mostly by chemical or thermal energy.

Answer 3

Ecosystems get their energy from the sun and it is transfered into producers which is then eaten by the next level on the trophic pyramid. every trophic level ønly gets 10% of the energy below it when consumed, the rest being lost in the form of heat energy.

Answer 4

The sun.
