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.
Heat from Earth's interior.
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 ultimate source of energy for terrestrial ecosystems is sunlight. Plants capture sunlight and convert it into chemical energy through photosynthesis, which is then passed on to consumers in the food chain. Without sunlight, photosynthesis cannot occur, and the ecosystem would not have the energy needed to sustain life.

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.
