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.
In total, energy leaves Earth's surface through three processes: evaporation and condensation (or latent heating and cooling), convection, and emission of thermal infrared radiation. Of these three processes, 25 percent of the energy that leaves the surface of the Earth is through evaporation and condensation.
