Solar energy enters the ecosystem through photosynthesis
The energy that is harnessed from photosynthesis enters the ecosystems of our planet continuously and is transferred from one organism to another. Therefore, directly or indirectly, the process of photosynthesis provides most of the energy required by living things on Earth. Photosynthesis also results in the release of oxygen into the atmosphere. - Download [PDF]

5: Photosynthesis
Through photosynthesis, certain organisms convert solar energy (sunlight) into chemical energy, which is then used to build carbohydrate molecules. The energy used to hold these molecules together is released when an organism breaks down food. 5.2: The Light-Dependent Reactions of Photosynthesis How can light be used to make food?
Energy Flow (Ecosystem): Definition, Process & Examples
Energy enters ecosystems as sunlight and is transformed into usable chemical energy by producers such as land plants, algae and photosynthetic bacteria. Once this energy enters the ecosystem via photosynthesis and is converted into biomass by those producers, energy flows through the food chain when organisms eat other organisms.
