photosynthesis
Photosynthesis - the capture of light energy by plants and its transformation into chemical energy.
The sun is the ultimate source of energy for almost all earth ecosystems.

Solar energy.
The main energy source for a reaction is typically provided by heat, light, or electricity.
The sun is the main sourse.

The Sun
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.
Exothermic reaction
The main source of energy for ecosystems is sunlight, which is harnessed by primary producers, such as plants and phytoplankton, through the process of photosynthesis. These producers convert solar energy into chemical energy in the form of glucose, forming the foundation of food webs. Other energy sources can include geothermal energy in certain ecosystems and organic matter from decomposed organisms, but sunlight remains the dominant energy source for most ecosystems on Earth.
The primary source of energy for photosynthesis is sunlight. The light energy is absorbed by chlorophyll in plant cells and is converted into chemical energy in the form of glucose through a series of biochemical reactions. This process is essential for plants to produce their own food and release oxygen as a byproduct.
