The Sun
Solar energy.
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.
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 most reliable source of energy for life on Earth is the Sun. Solar energy provides the necessary light and heat for photosynthesis, which is the process by which plants and other organisms convert sunlight into energy. This energy powers most ecosystems and is essential for sustaining life on our planet.
