Grasslands of BC :: Ecosystems. Energy Flow. Refer to the yellow arrows in the diagram to help you understand the way that energy moves through an ecosystem. Energy enters an ecosystem in the form of heat from the sun. This energy is absorbed by organisms such as plants, and is then converted to other forms of energy and stored. Once stored, energy is used for necessary life functions, such as growth, movement and reproduction.
Energy flow is the capture of solar energy through photosynthesis, which is the process used by green plants to convert radiant energy from the sun into organic compounds such as glucose.olar energy flow is not a cycle, but a flow from the sun to the biosphere. It is one of the four basic ecosystem processes or windows through which we can begin to perceive the ecosystem as a whole. The others are the water cycle, mineral cycles, and community dynamics or ecological succession.
